Question

What is the probability of pulling out two yellow marbles?

Answer 1

2/ 17 because it’s 17 marbles and I hav a 2/17 chance of pulling 2 yellows

Answer 2

Explanation:

n(Y) = 8

Total marble = 8+4+5 = 17

Prob(1st Y) = 8/17

2nd been yellow means number of yellow left is 7 ant total number of marble is 16

Prob(2nd Y) = 7/16

Prob(1st Y and 2nd Y)= 8/17 × 7/16

= 7/34
