1. Because *n* = 10, *r* = 7, *p* = 0.5

2. Because *n* = 6, *r* = 3, *p* = 0.75

3. The probability of making at least 6 of 8 is P[6,8] + P[7,8] + P[8,8]. Because *n* = 8, *p* = 0.8

Therefore, the probability of making at least 6 out of 8 is 0.2936 + 0.3355 + 0.1678 = 0.7969.

4. Because *n* = 12, *r* = 6, *p* = 0.2

5. The probability of no more ...
