Answer:
What is PR3 jG1 , the conditional probability that 3 is rolled given that the roll is greater than 1
=0,02
Step-by-step explanation:
Sample Space for rolling a die, S(1,2,3,4,5,6]
Since all the outcomes are equally P( rolling any numebre)=1/6
G1=(2,3,4,5,6)
Hence P(G1) =P (R2)+P (R3)+P (R4)+P (R5)+P (R6)
Hence P(G1) =5/6
and R3= [3]
Hence G1 ∩ R3 = [3] = R3
Hence P(G1 ∩ R3) =P( R3) =1/6
What is PR3 jG1 , the conditional probability that 3 is rolled given that the roll is greater than 1
P(G1 ∩ R3) / P(G1) = (1/6)/ (5/6=
=0,02
In a class of 26 students, 11 are female and 10 have an A in the class. There are 2 students who are female and have an A in the class. What is the probability that a student is a female given that they have an A?
The probability that a student is a female given that they have an A is 0.2
How to determine the probability?The given parameters are:
Female = 11
A= 10
Female and A = 2
The probability is calculated using:
P(Female given A) = P(female and A)/P(A)
This gives
P(Female given A) = 2/10
Simplify
P(Female given A) = 0.2
Hence, the probability that a student is a female given that they have an A is 0.2

We shuffle a deck of cards and deal three cards (without replacement). Find the probability that the first card is a queen, the second is a king, and the third is an ace.
Answer:
the probability that the first card is a queen, the second is a king, and the third is an ace is 0.000482655
Step-by-step explanation:
Given the data in the question;
we know that a deck of cards contains 52 cards
3 cards are dealt out without replacement
probability that first card is queen, the second is king and third is an ace will be;
P(First is a King, second is a Queen, third is an Ace) = [ 4/52 ] × [ 4/51 ] × [4/50]
= 64 / 132,600
= 0.000482655
Therefore, the probability that the first card is a queen, the second is a king, and the third is an ace is 0.000482655

The ratio of the number of text messages sent by Diego to the number of text messages sent by his sister is 3 to 4. Diego sent 18 text messages. How many more text messages did his sister send?
Answer:
His sister sent 6 more messages than Diego.
Step-by-step explanation:
Ratio of Diego's messages to his sister's messages = 3 : 4
Text messages sent by Diego = 18
Text messages sent by his sister = x
Ratio = 18 : x
It is a proportional relationship,
3 : 4 :: 18 : x
Product of extremes = Product of means
3x = 18*4
3x = 72
[tex]\frac{3x}{3}=\frac{72}{3}\\x=24[/tex]
Difference = 24 - 18 = 6
Therefore,
His sister sent 6 more messages than Diego.

Caviar is an expensive delicacy, so companies that package it pay very close attention to the amount of product in their tins. Suppose a company that produces over 1000 tins of caviar per day took an SRS of 20 tins from one day's production. The sample showed a mean of 99.8g of caviar per tin with a standard deviation of 0.9g. The data were roughly symmetric with no outliers.
Required:
Based on this sample, estimate with 95, percent confidence the mean amount of caviar (in grams) per tin from that day's production.
Answer:
95% of the confidence interval of the mean amount of caviar per tin from that day's production
(99.3788.100.2212)
Step-by-step explanation:
Step(i):-
Given that the size of the sample 'n' = 20
Given that mean of the sample = 99.8 g
Given the standard deviation of the sample = 0.9g
Level of significance = 0.05
[tex]t_{\frac{0.05}{2} ,19} = t_{0.025,19} = 2.093[/tex]
Step(ii):-
95% of the confidence interval of the mean amount of caviar per tin from that day's production
[tex](x^{-} - t_{0.025,19} \frac{S}{\sqrt{n} } , x^{-} + t_{0.025,19} \frac{S}{\sqrt{n} })[/tex]
[tex](99.8 - 2.093 \frac{0.9}{\sqrt{20} } , 99.8 + 2.093 \frac{0.9}{\sqrt{20} })[/tex]
on simplification, we get
(99.8 -0.4212 , 99.8+0.4212)
(99.3788.100.2212)
Final answer:-
95% of the confidence interval of the mean amount of caviar per tin from that day's production
(99.3788.100.2212)
The confidence interval with 95% confidence where the mean amount of caviar (in grams) per tin from that day's production is [tex]\bold{99.8 \pm 0.9344}[/tex].
Given to us,
size of the sample, n = 20,
mean of the sample, [tex]\bar{x}[/tex] = 99.8 g
the standard deviation of the sample, σ = 0.9g
As, we know, the confidence level value for 95% confidence is 1.960.
[tex]z = 1.960[/tex]
Also, the formula for the confidence interval is given as,
[tex]CI = \bar{x} \pm z \dfrac{s}{\sqrt{n}}[/tex]
where,
CI = confidence interval
[tex]\bar{x}[/tex] = sample mean
z = confidence level value
σ = sample standard deviation
n = sample size
For, 95% of the confidence interval of the mean amount of caviar per tin from that day's production,
[tex]CI = \bar{x} \pm z \dfrac{\sigma}{\sqrt{n}}[/tex]
substituting the values,
[tex]\begin{aligned}CI &= 99.8 \pm (1.960) \dfrac{0.9}{\sqrt{20}}\\&=99.8 \pm 0.9344\\\end{aligned}[/tex]
Hence, the confidence interval with 95% confidence where the mean amount of caviar (in grams) per tin from that day's production is [tex]\bold{99.8 \pm 0.9344}[/tex].

solutions to 2-variable equations y=-2x-5
Answer:(1, -3).
Step-by-step explanation:
If y=2x-5 is equation (1) and 4x-y=7 is equation (2), then substitute equation (1) in equation (2):
4x - (2x - 5) = 7
4x - 2x + 5 = 7
2x = 7-5
2x = 2
x = 1
Now substitute the value of x in equation (1) to find the value of y:
y = 2 (1) - 5
y = 2 - 5
y = -3
