OpenStudy (sleepyjess):

Not quite, a person wearing white shoes among the group of females.

OpenStudy (anonymous):

OpenStudy (sleepyjess):

Add up all of the females

OpenStudy (anonymous):

OpenStudy (sleepyjess):

Lets reword it slightly, given that the person is a female, find the probability they are wearing white shoes.

OpenStudy (anonymous):

so A????

OpenStudy (sleepyjess):

Hmmm..... remember, the smaller number goes on top

OpenStudy (anonymous):

OpenStudy (anonymous):

i didvided 16 by 33 and rounded

OpenStudy (sleepyjess):

Yep! You originally said 33/16, which is 33 divided by 16.

OpenStudy (anonymous):

OpenStudy (sleepyjess):

Yes, you have to do 16/33. Yep, it is A
