The manager of an online music store has kept records of the number of songs downloaded in a single transaction by customers who make a purchase at the store. Consider the chance experiment of observing the number of songs downloaded by a randomly selected customer. The accompanying table gives six possible outcomes and the estimated probability of each of these outcomes. Number of songs downloaded Estimated probability 1 0.30 2 3 4 5 0.25 0.15 0.15 0.10 6 or more 0.05 (a) What is the estimated probability that a randomly selected customer downloads five or more songs? (b) What is the estimated probability that a randomly selected customer downloads one or two songs? (c) What is the estimated probability that a randomly selected customer downloads more than two songs? Show two different ways to compute this probability that use the probability rules of this section. (Select all that apply.) ☐ 1 - P(less than 2) 1- P(2 or fewer) OP(2) + P(3) + P(4) + P(5) + P(6 or more) P(3) + P(4) + P(5) + P(6 or more) OP(more than 3) - P(less than 2) OP(3 or more) - P(2 or fewer)
