Seventeen candidates have filed for the upcoming county council election. 7 are women and 10 are men a) Is how many ways can 10

tankabanditka [31]

Answer: (a) 19448 ways

(b) 5292 ways

(c) 0.2721

Step-by-step explanation:

(a) 10 county council members be randomly elected out of the 17 candidates in the following ways:

= $^{n}C_{r}$

= $^{17}C_{10}$

= $\frac{17!}{10!7!}$

= 19448 ways

(b) 10 county council members be randomly elected from 17 candidates if 5 must be women and 5 must be men in the following ways:

we know that there are 7 women and 10 men in total, so

= $^{7}C_{5}$ × $^{10}C_{5}$

= $\frac{7!}{5!2!}$ × $\frac{10!}{5!5!}$

= 21 × 252

= 5292 ways

= $\frac{ ^{7}C_{5} * ^{10}C_{5}}{^{17}C_{10}}$

= $\frac{5292}{19448}$

= 0.2721
