Question

Three balls are drawn from a box containing 6 red marbles, 4 white marbles and 5 blue marbles. Find the probability that they are drawn in the order: red, white, and blue if each ball is drawn with replacement

Answer 1

are you currently covering conditional probability?

Answer 2

yep u got preparing for exams

Answer 3

I'm not sure if it is

P(red AND white AND blue) or if it is P(red|white|blue)

Answer 4

oh, one sec i think i got this.

Answer 5

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

Answer 6

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).
