Question 1185496: Assume this year's flu vaccine has a 75% chance of being effective. If the vaccine is given to 338 randomly selected people, answer the following.
a) Which is the correct wording for the random variable?
b) Pick the correct symbol: n = 338
c) Pick the correct symbol: p = 0.75
d) What is the probability that exactly 252 of them did not get the flu?
Round final answer to 4 decimal places= 0.0489
e) What is the probability that less than 252 of them did not get the flu?
Round final answer to 4 decimal places= 0.3971
f) What is the probability that more than 252 of them did not get the flu?
Round final answer to 4 decimal places= ?
g) What is the probability that exactly 257 of them did not get the flu?
Round final answer to 4 decimal places= ?
h) What is the probability that at least 257 of them did not get the flu?
Round final answer to 4 decimal places= 0.3565
i) What is the probability that at most 257 of them did not get the flu
Round final answer to 4 decimal places= 0.6895

Too many questions for one post.

The rule of this forum is one problem/question per post.

If to imagine that the rule is made of rubber, then 2, not more than 3 questions per post.

But not 9 questions, as in your post.


9 questions - it is just the size of a MS thesis (a joke).
