Assuming you are listening to your favorite playlist that has 83 country songs, but your mom also added 9 pop. Suppose that shuffle mode is on - a song played is being selected at random (with replacement) from the playlist. Find the probability that, out of the next 13 songs, at most one will be pop song.

Answer 1

P(pop) = 9/92
so,
P(0 pop) = (83/92)^13
P(1 pop) = 13C1 (9/92)(83/92)^12
add them up

Answer 2

@steve,

Please I'm not clear with what you mean by 13C1. Thanks

Answer 3

I got it now. 13 combination 1. Thanks
