Chapter 5: Probability Distributions Binomial Probabilities Consider the binomial probabilities corresponding to n = 4 and p = 1/4 (or 0.25). If you attempt to use Table A-1 for finding the probabilities, you will find that the table does not apply to a probability of p =1/4. Use Statdisk to find the probabilities 5-5 and enter the results below. P(0) =. P(1) =, P(2) =, P(3) = P(4) =- revious
