A bag contains 8 red marbles, 4 white marbles, and 5 blue marbles. You draw one marble at random. Find P(red and blue).

OpenStudy (kirbykirby):

How can you draw a red and blue one, if you only draw one? Do you mean P(red or blue) ?

OpenStudy (anonymous):

thats what I'm confused about

OpenStudy (kirbykirby):

Honestly this doesn't make sense. Whoever wrote this question made a typo I'm sure.

OpenStudy (kirbykirby):

Either you draw 2 marbles, or you have P(red or blue)...
