Match the proposed probability of A with the appropriate verbal description A letter is chosen at random from the word "CAROL". What is the probability that it is a vowel? Fifteen persons reporting to a Red Cross center one day are typed for blood, and the following counts are found: For two events A and B, the following probabilities are given. Use the appropriate laws of probability to calculate: For two events A and B, the following probabilities are given. P(A) = 0.5, P(B) = 0.15, P(A | ...

Question 1 1. If two events are not mutually exclusive, then P(A or B) = P(A) P(B) True False 2 points Question 2 1. Seventy two percent of all observations fall within 1 standard deviation of the mean if the data is normally distributed. True False 2 points Question 3 1. Probability trees are used only to compute conditional probabilities. True False 2 points Question 4 1. The equal likelihood criterion assigns a probability of 0.5 to each state of nature, regardless of how many...
