How does one solve an equation like this?
In 1995, 70% of all children in the U.S. were living with both parents. If 25 children were selected at random in the U.S., what is the probability that at least 15 of them will be living with both of their parents? Round your answer to 4 decimal places.

Probability of one is 7/10
Probability of multiple things happening at the same time is the product of all probabilities, therefore
Answer = (7/10)^15
= .0047
