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.
