six claims are to be randomly selected from a group of thirteen different claims, which includes two workers compensation claims, four homeowners claims and seven auto claims.

calculate the probability that the six claims selected will include one workers compensation claim, two homeowners claims and three auto claims

Answers

Using the combination formula, it is found that there is a 0.2448 = 24.48% probability that the six claims selected will include one workers compensation claim, two homeowners claims and three auto claims.

A probability is the number of desired outcomes divided by the number of total outcomes.In this problem, the order in which the claims are chosen is not important, which means that the combination formula is used to find these numbers of outcomes.

Combination formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The desired outcomes are:

One workers from a set of 2.Two homeowners from a set of 4.Three auto-claims from a set of 7.

Thus:

[tex]D = C_{2,1}C_{4,2}C_{7,3} = \frac{2!}{1!1!} \times \frac{4!}{2!2!} \times \frac{7!}{4!3!} = 420[/tex]

For the total outcomes, six claims from a set of 13, thus:

[tex]T = C_{13,6} = \frac{13!}{6!7!} = 1716[/tex]

The probability is:

[tex]p = \frac{D}{T} = \frac{420}{1716} = 0.2448[/tex]

0.2448 = 24.48% probability that the six claims selected will include one workers compensation claim, two homeowners claims and three auto claims.

A salesman earns 60% commission on all the merchandise that he sells. Last month he sold $800 worth of merchandise. How much commission (in dollars) did
he earn last month?

Answers

Answer:

Step-by-step explanation:

✓ Step-by-step explanation:commission earned = 60% of $800800 × 60/100 = $480

The Commission (in dollars) he earn last month is $480.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

A salesman earns 60% commission on all the merchandise that he sells. Last month he sold $800 worth of merchandise.

So, the Commission he earns

= 800 + 800 x 60%

= 800 + 800 x 60/100

= 800 + 480

= 1280

Hence, the commission is $480.

Step-by-step explanation:

Intersecting lines make equal opposite angles

2x + y = 50 - y

     2x = 50 - 2y

       x = 25 - y

A straight line represents 180°

4x + 6y + 2x + y + 2x + 3y = 180

                            8x + 10y = 180

                  8(25 - y) + 10y = 180

                  200 - 8y + 10y = 180
