are you currently covering conditional probability?

yep u got preparing for exams

anonymous · Answer

I'm not sure if it is 

P(red AND white AND blue) or if it is P(red|white|blue)

anonymous · Answer

oh, one sec i think i got this.

anonymous · Answer

P(pulling a red on the first one) = 6/15

Draw them one by one, each time putting it back.
You want to know: P(r,w,b).
So: 
Draw 1st. P(red)=6/15.
Draw 2nd. P(white)=4/15.
Draw 3rd. P(blue)=5/15.

Multiply those probabilities to find P(r,w,b).
