Suppose we want to determine the (binomial) probability (p) of getting 5 heads in 15 flips of a 2-sided coin. Using the Binomial table in the appendix of the text, what values of n, x, and p would we use to look up this probability, and what would be the probability?
Learning is a lifetime activity. For some, it means learning from everyday experiences; for others, it means taking classes in a more traditional atmosphere. The percentage of people participating in organized learning situations during 2002 for each age group is reported here by NIACE.
Age Group 17-19 20-24 25-35 35-44 45-54 55-64 65-74 75+ All
Percentage 78 72 51 49 44 30 20 10 42
Is this a probability distribution? Explain why or why not.
