How do I find the cost for the sales tax if the price is $7 and the sales tax is 8% or 0.08
galina1969 [7]
Multiply 7 by 0.08 and you get $0.56. $0.56 is the tax. For other tax questions just multiply the price and the sales tax as the decimal.

brilliants [131]

Answer:

0.18% probability that they are all women

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the senators are chosen is not important, so the combinations formula is used to solve this question.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

Desired outcomes:

3 women, from a set of 13. So

D = C_{13,3} = \frac{13!}{3!(13 - 3)!} = 286

Total outcomes:

3 senators, from a set of 100. So

T = C_{100,3} = \frac{100!}{3!(100 - 3)!} = 161700

Probability;

p = \frac{D}{T} = \frac{286}{161700} = 0.0018

0.18% probability that they are all women
