Answer:

5/22

Step-by-step explanation:

A bag has 6 blue marbles, 4 red marbles, and 2 green marbles. Wo marbles are randomly chosen without replacement.

Total number of marbles =

6 blue marbles + 4 red marbles + 2 green marbles

= 12 marbles

The probability of picking a blue marble = P(B) = 6/12

Therefore, the probablilty that both marbles picked are blue without replacement is

= 6/12 × 5/11

= 30/132

= 5/22
