1. According to a local survey 76% Angelino are Llakers fan. If you randomly select five Angelinos:

a)what is the probability that all are lakers fans?
I did 0.76^5 and that = 0.2536

b)what is the probability that none of them are Lakers fans?
I did 0.24^5 and that = 0.0007963

c)what is the probability that one is a Lakers fan?
1 - 0.0007963 = 0.9992

Did I do this correct?

2. If you flip a coin and throw two dice at the same time, what is the probability that you will get a "face" and two "4's"?

To get a face is 1/2 (.5) and to get two 4's while rolling two dice is 1/36 (.0277) then you would multiply those both and get .01385

First time taking statistics, all really new and confusing.

It appears to me that you did everything correctly except possibly (1c). What does "what is the probability that one is a Lakers fan?" mean? Is that exactly one is a Lakers fan or is it at least one is a Lakers fan? You have correctly answered if it is the 'at least one is a Lakers fan' question.
