Let X represent the number of homes a real estate agent sells during a given month. Based on previous sales records, she estimates that Upper P left parenthesis 0 right parenthesis equals 0.63, Upper P left parenthesis 1 right parenthesis equals 0.21, Upper P left parenthesis 2 right parenthesis equals 0.12, Upper P left parenthesis 3 right parenthesis equals 0.03, Upper P left parenthesis 4 right parenthesis equals 0.01, with negligible probability for higher values of x. a. Explain why it does not make sense to compute the mean of this probability distribution as left parenthesis 0 plus 1 plus 2 plus 3 plus 4 right parenthesis divided by 5 equals 2.0. b. Find the correct mean and interpret.

Adeli charges the same price, $5.50, for all of its different sandwiches. if a company ordered n sandwiches for a luncheon, which equation could be used to find the total price, p, that the deli charged for the sandwiches? a- n/5.50=p b-5.50n=p c-5.50/n=p d-5.50+n=p

In a sample of 2023 u.s. adults, 373 said franklin roosevelt was the best president since world war ii. two u.s. adults are selected at random from the population of all u.s. adults without replacement. assuming the sample is representative of all u.s. adults, complete parts (a) through (d). (a) find the probability that both adults say franklin roosevelt was the best president since world war ii. the probability that both adults say franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (b) find the probability that neither adult says franklin roosevelt was the best president since world war ii. the probability that neither adult says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (c) find the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii. the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (d) which of the events can be considered unusual? explain. select all that apply. the event in part left parenthesis a right parenthesis is unusual because its probability is less than or equal to 0.05. the event in part (b) is unusual because its probability is less than or equal to 0.05. none of these events are unusual. the event in part (c) is unusual because its probability is less than or equal to 0.05.
