Answer:
5/16.
Explanation:
Prob(Red picked from the first bag) = 1/4.
Prob(Blue picked from the second bag) = 1/4.
Probability of these 2 events occurring = 1/4 * 1/4 = 1/16.
But there is another scenario where a blue is picked from the first bag and a red from the second
Probability of this is 2/4 * 2/4 = 1/4.
So the required probability is 1/16 + 1/4 = 5/16.
