random sample of 50 college students?

Question

Suppose that 60% of college students eat pizza weekly. Answer the following questions if you have a random sample of 50 college students.

1. What is the probability that exactly 29 eat pizza weekly?
2. What is the probability that 35 or fewer eat pizza weekly?
3. What is the probability that more than 32 eat pizza weekly?
4. Round each answer to four decimal places.
5. 
   

Answer 1

P(X=29|Binomial(n=50:p=.6))=.1091

P(X<=35|Binomial(n=50:p=.6))=.9460

P(X>32|Binomial(n=50:p=.6))=1-P(X<=32|Binomial(n=50:p=.6))=1-.7631=.2369
