Question 615853: Can someone please help I am still not understanding.
Suppose we want to determine the (binomial) probability (p) of getting 0 (zero) heads in 5 flips of a 2-sided coin. Using Table 2 in Appendix B of the text, what values of n, x, and p would we use to look up this probability, and what would be the probability?
I know that n= 5 and x= O p=0.05
The table
n x 0.01 0.05 0.10 0.20 0.30 0.40 0.50 0.60 0.70
5 0 .951 .774 .590 .328 .168 .078 .031 .010 .002

You can put this solution on YOUR website! The probability is really p = 0.5 (since 1/2 = 0.5)
Now look for the value of p = 0.5 (in green). Below is the answer (in red)
n x 0.01 0.05 0.10 0.20 0.30 0.40 0.50 0.60 0.70
5 0 .951 .774 .590 .328 .168 .078 0.031 .010 .002
Answer: So the probability of getting exactly 0 heads in 5 flips is approximately 0.031
