In a major midwestern university, 60% of all undergraduates are female, 30% belong to a greek organization (fraternity or sorority) and 40% of all males belong to a greek organization. what is the probability that an undergraduate is in a greek organization given that the undergraduate is a female?

30% probability that an undergraduate is in a greek organization given that the undergraduate is a female

Step-by-step explanation:

The conditional probability formula is used to solve this question:

In which

P(B|A) is the probability of event B happening, given that A happened.

is the probability of both A and B happening.

P(A) is the probability of A happening.

In this problem, we have that:

60% of undergraduates are female.

100 - 60 = 40% are male.

30% belong to the organization.

Of those, 40% are male.

So 0.3*0.4 = 0.12 are male and belong to the organization.

0.3 - 0.12 = 0.18 are female and belong to the organization.

What is the probability that an undergraduate is in a greek organization given that the undergraduate is a female?

Event A: Being female, so P(A) = 0.6.

Event B: Being in the organization.

So

30% probability that an undergraduate is in a greek organization given that the undergraduate is a female

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
