Answer:
60*220 feet = 13,000 Feet convert to Miles = 2.462121 miles/hr
Step-by-step explanation:
Since the events are independent and can be reduced to two outcomes, we can solve it using the binomial formula.
A. 9 only bc only 9 can be equal to 9 if it was absolutely value then the answer would be 9 and -9
You only need to consider the situations where 10 or 11 of the babies are girls, then subtract those probabilities from 1. This will give probability that any other number up to 9 of the babies are girls.
Use binomial theorem.

n = 11
k = 10,11
p = 1/2
