In a sales effectiveness seminar, a group of sales representatives tried two approaches to selling a customer a new automobile: the aggressive approach and the passive approach. For 1160 customers, the following record was kept: Suppose a customer is selected at random from the 1160 participating customers. Let us use the following notation for events: A = aggressive approach, Pa = passive approach, S = sale, N = no sale. So, P(A) is the probability that an aggressive approach was used, and so on. (a) Compute P(S), P(S | A), and P(S | Pa). (Enter your answers as fractions.) Simplify the fraction if needed P(S) = ? P(S | A) = ? P(S | Pa) = 95/116 (b) Compute P(A and S) and P(Pa and S). (Enter your answers as fractions.) Simplify the fraction if needed P(A and S) = ? P(Pa and S) = 95/232 (c) Compute P(N) and P(N | A). (Enter your answers as fractions.) Simplify the fraction if needed
In a survey of consumers aged 12 and older, respondents were asked how many cell phones were in use by the household. (No two respondents were from the same household.) Among the respondents, 211answered "none,"289 said "one," 373 said "two," 143 said "three," and 138 responded with four or more. A survey respondent is selected at random. Find the probability that his/her household has four or more cell phones in use. Is it unlikely for a household to have four or more cell phones in use? Consider an event to be unlikely if its probability is less than or equal to 0.05.

Dr. Deming’s Red Bead Experiment is an exercise in the laws of probability. The workers were frustrated because no matter what they did, the outcome was not predictable. If the paddle holds 50 beads and there are 500 white beads and 50 red beads in the box, what is the probability, using one sample, of filling a paddle with 47 white beads and only three red beads? Give your answer as a percentage and share how you arrived at your conclusion
A researcher wishes to conduct a study of the color preferences of new car buyers. Suppose that 50% of this population prefers the color red. If 12 buyers are randomly selected, what is the probability that exactly 10 buyers would prefer red? Round your answer to four decimal places.
