1. ## Binomial distributions

A total of 16 mice are sent down a maze, one by one. From previous experience, it is
believed that the probability a mouse turns right is .38

a) What is the probability that exactly 8 of these 16 mice turn right?
b) What is the probability that 8 or fewer turn right?
c) What is the probability that 8 or more turn right?
d) What is the probability that more than 3, but fewer than 10 turn right?
e) What is the probability that exactly 10 turn left?

I have been trying this for over an hour and can't seem to figure it out..
So far I have gotten a) 0.122 and e) 0.202 but i'm not even sure these are correct.

Well, so far so good, i.e. both of your answers for a) and e) are correct.
