Answer with explanation please!


1.Suppose two students are selected at random.
a. What is the probability that the first student was born in November?
b. What is the probability that both students were born in December?

2.Let E be the event that a randomly selected person in the U.S. who is over the age of 24 has attended college. Let F be the event that a randomly selected U.S. resident over the age of 24 is female. According to the U.S. Census Bureau,
P(E) = 0.559 and P(F) = 0.518, and P(E and F) is 0.295. (Source: U.S.

Solution

Note we are suppose to answer one question at a time so i will give u answer of 1st for rest repost again.

1)a) as november has 30 days in a month so any one can born in this 30 days

so the chances of being a november born comes out to be = 30/365

b) for both being a december born we will take the sqaure of chances of 1 being a december born

that is chances of 1 being december born as december has 31 days so probability = 31/365

therefore chances both being december born is (31/365)^2 = 961/133225
