Question
Two professors are applying for grants. Professor Jane has a probability of 0.68 of being funded. Professor Joe has probability 0.25 of being funded. Since the grants are submitted to two different federal agencies, assume the outcomes for each grant are independent.
Give your answer to four decimal places.
a. What is the probability that both professors get their grants funded? 1
b. What is the probability that at least one of the professors will be funded? 2
c. What is the probability that Professor Jane is funded but Professor Joe is not? 3
d. Given at least one of the professors is funded, what is the probability that Professor Jane is funded but Professor Joe is not? 4
Explanation / Answer
let probabiliy of Professor Jane funded =P(A) =0.68
probabiliy of Professor Joe funded =P(B) =0.25
a) for independence probability that both professors get their grants funded P(AnB) = =0.68*0.25=0.17
b) probability that at least one of the professors will be funded =P(AUB) =P(A)+P(B)-P(AnB)
=0.68+0.25-0.17=0.76
c)probability that Professor Jane is funded but Professor Joe is not P(AnBc)=P(A)-P(AnB) =0.68-0.17 =0.51
d) probability that Professor Jane is funded but Professor Joe is not given at least one funcded
=P(AnBc)/P(AUB) =0.51/0.68 =3/4 =0.75
