A pencil holder contains six blue pencils and three red pencils. What is the probability that two blue pencils are drawn at random?​

step 1

Find out the probability that one blue pencil is draw at random

P=6/9

step 2

Find out the probability that the second blue pencil is draw at random

P=5/8

step 3

Find out the probability that two blue pencils are drawn at random

P=(6/9)*(5/8)

P=30/72

simplify

P=15/36

P=5/12

therefore

the answer is 5/12
