HELP PLEASE DON'T GET IT A basketball player gets 2 free-throw shots when she is fouled by a player on the opposing team. She misses the first shot 40% of the time. When she misses the first shot, she misses the second shot 5% of the time. What is the probability of missing both free-throw shots?

OpenStudy (anonymous):

@phi please help me

OpenStudy (phi):

you multiply the probability of missing the first times prob of missing the 2nd what is the prob of missing the first?

OpenStudy (anonymous):

40%

OpenStudy (phi):

yes, or 0.4 what is the prob of missing the 2nd? (and we have to assume we missed the first, because we are looking for the prob of missing both)

OpenStudy (anonymous):

5% or 0.05

OpenStudy (phi):

now multiply 0.4*0.05

OpenStudy (anonymous):

you get 0.02 or 2%

OpenStudy (phi):

yes

OpenStudy (anonymous):

so that is the answer 2%

OpenStudy (phi):

yes
