Question

Tate has bag of golf balls 3 red, 5 blue, 2 yellow, and 2 green. What is the probability that he pulls out a red one, replaces it, and then pulls out another red one?

Answer 1

here is the answer mate..

total golf balls =12

red balls =3

so, probability of red balls=3/12

now,he pulls out the another red one..

so, probability of another red one still remains same=3/12

hence.probability of both=3/12

1/4*1/4

1/16= answer.

hope u understand dear...
