Answer:

25/49

Step-by-step explanation:

we will use AND OR rule here

(red marble AND red marble) OR (blue marble AND blue marble)

AND means Multiplication

OR means addition

probability of getting red marble = 3/7

probability of getting blue marble = 4/7

(3/7×3/7)+(4/7×4/7) = 25/49

HOPE IT HELPS ;)
