Answer:
r equals StartFraction C Over 2 pi EndFraction
Step-by-step explanation:
we know that
The circumference of a circle is equal to

where
r is the radius of the circle
Solve for r
That means -----> isolate the variable r
Divide by 2π both sides

Simplify right side

Rewrite

so
r equals StartFraction C Over 2 pi EndFraction
Answer with explanation:
Given : Number of men = 4
Number of women = 6
Total people = 
Total number of ways to make a committee of five people from 10 persons :-

a) Number of ways to make committee that has exactly four women :

The probability that committee has exactly four women :

b) Number of ways to make committee that has at-least four women :

c) Number of ways that committee has more than 4 women :-

The probability that committee has more than 4 women :-

Now, the probability that committee has at most four women :-

X is 3
