www.g "A political discussion group consists of 6 Democrats and 10 Republicans. Three members are selected to attend a conferenc
stealth61 [152]

Answer:

Probability = \frac{3\\}{14}

Step-by-step explanation:

Given

Republicans = 10

Democrats = 6

Total = Republicans + Democrats = 10 + 6 = 16

Selection = 3

Required

Probability that all selected members are Republicans

This implies that all selected members are republicans and none are republicans

This is calculated by (Number of ways of selecting 3 republicans * Number of ways of selecting 0 Democrats) / (Total number of possible selections)

First; the number of ways the 3 republicans from 10 can be selected needs to be calculated;

^{10}C_3 = \frac{10!}{(10-3)!3!}

^{10}C_3 = \frac{10!}{7!3!}

^{10}C_3 = \frac{10*9*8*7!}{3!7!}

Divide numerator and denominator by 7!

^{10}C_3 = \frac{10*9*8}{3*2*1}

^{10}C_3 = \frac{720}{6}

^{10}C_3 = 120

Next, the number of ways that 0 republicans can be selected from 6 will be calculated

^6C_0 = \frac{6!}{(6-0)!0!}

^6C_0 = \frac{6!}{6!0!}

^6C_0 = 1

Next, the total number of possible selection will be calculated; In other words number of ways of selecting 3 politicians fro a group of 16

^{16}C_3 = \frac{16!}{(16-3)!3!}

^{16}C_3 = \frac{16!}{13!3!}

^{16}C_3 = \frac{16*15*14*13!}{13!3!}

^{16}C_3 = \frac{16*15*14}{3!}

^{16}C_3 = \frac{16*15*14}{3*2*1}

^{16}C_3 = \frac{3360}{6}

^{16}C_3 = 560

Lastly, the probability is calculated as follows;

Probability = \frac{^{10}C_3\ *\ ^6C_0}{^{16}C_3}

Probability = \frac{120\ *\ 1}{560}

Probability = \frac{120\\}{560}

Simplify fraction to lowest term

Probability = \frac{3\\}{14}
