Answer 1

25/49

Explanation:

we will use AND OR rule here

same color in both cases means

(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
