The probability that the fourth marble Amy picks is black: This probability cannot be determined without knowing the total number of marbles and the number of black marbles.
The probability that, if Amy picks a black marble in the fourth attempt, she will pick a red or a black marble in the fifth attempt: This probability cannot be determined without knowing the total number of marbles and the number of red and black marbles.
Probability is a measure of the likelihood of an event occurring. To calculate the probability of an event, you need to know the total number of outcomes and the number of outcomes that are favorable to the event. For example, if there are 10 marbles in total and 4 of them are black, the probability that Amy will pick a black marble on the fourth attempt is:
Probability = Number of black marbles / Total number of marbles = 4/10 = 0.4
Similarly, if Amy picks a black marble in the fourth attempt and there are a total of 10 marbles, with 4 of them being black and 6 of them being red, the probability that she will pick a red or a black marble in the fifth attempt is:
Probability = (Number of red marbles + Number of black marbles) / Total number of marbles = (6 + 4) / 10 = 0.8

I am not allowed to use a calculator, by the way.
Step-by-step explanation:
(38+45)+9*2+3-59+((4/2)*3+8*5)=
83+18+3-59+(6+40)=
83+18+3-59+(6+40)=
83+18+3-59+46=
(83+18+3+46)-59=
150-59=91
I'm not sure if this is correct but it should be. Is it 4/2*3 or (4/2)³?If it is (4/2)³ the result would be 93.

The drama department was considering two options for the winter production. They used the following equations to represent the profit, y, they
would make from the sale of tickets, x, minus the costs.
Option A: y= 5x - 1500
Option B: y = 3x - 500
Which graph correctly shows the point after which Option A becomes more profitable than Option B?
Answer:
Graph D is correct
Step-by-step explanation:
This is complicated because the scales on the x-axis and y-axis are not the same. Graph D has the correct y-intercepts and the correct slopes. The solution is x = 500, where the two lines intersect.

someone please help with this math question! ill give brainly if its correct
Answer:
x = 50, y = 61
Step-by-step explanation:
y + 8 + 2x + 11 = 180°
y + 2x = 161°
the total of the interior angles of the 5 sided polygon is:
(180 x 5) - 360 = 540°
540 = 98 + 98 + 125 + 108 + 2x + 11
2x = 100
x = 50°
y + 2(50) = 161
y = 61°
