Question

A bag has 3 white scraps,2 yellow scrapes,and 3 black scraps.You randomly pull a scrap from the bag,keep it out,and then pull out another one What is the probability of not getting a white and then not getting a white?Write your answer as a fraction

​

Answer 1

25/56

Explanation:

Prob of white = 3/8

Probability of not white = 1 - 3/8

= 5/8

Explanation:

Probability of white = 2/7

Probability of not white = 1 - 2/7

= 5/7

Total probability = 5/8 x 5/7

= 25/56

Answer 2

25/56

Explanation:

Prob of white = 3/8

Probability of not white = 1 - 3/8

= 5/8

Second pick without replacement

Probability of white = 2/7

Probability of not white = 1 - 2/7

= 5/7

Total probability = 5/8 x 5/7

= 25/56
