how many flowers are pink roses?

OpenStudy (anonymous):

120?

OpenStudy (anonymous):

table's difficult to read, but 120 looks like it's one of the totals. pink roses will be the box where PINK column intersects ROSE row

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

what'd you get?

OpenStudy (anonymous):

20

OpenStudy (anonymous):

ok so put that over the total number, 315 and divide to get the probability

OpenStudy (anonymous):
