Explanation:

Answer 2

0.243

Explanation:

Given that :

Probability of success (p) = 76% = 0.76

Number of free throws (n) = 10

Probability of making 7 free throws = r

Using binomial distribution :

nCr * p^r * (1 - p)^(n-r)

10C7 * 0.76^7 * (1 - 0.76)^(10 - 7)

10C7 * 0.76^7 * 0.24^3

120 * 0.14645 * 0.013824

= 0.24294

Hence probability of making 7 free throws from 10 is 0.243
