a veterinarian is using a new vaccine for cats. the vaccine has a 10% probability of causing side effects.

in which distributions does the variable x have a binomial distribution?

select each correct answer.

when the vaccine is given to three cats, x is the number of cats that have side effects.

when the vaccine is given to multiple cats, x is the total number of cats that receive the vaccine.

when the vaccine is given to multiple cats, x is the number of cats that receive the vaccine until one of them has side effects.

when the vaccine is given to six cats, x is the number of cats that do not have any side effects.

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.
