Answer:
13/15
Step-by-step explanation:
Case 1: A solves the problem and B does not
Probability = 2/3 * (1-3/5) = 4/15
Case 2: B solves the problem and A does not
Probability = (1-2/3) * 3/5 = 1/5
Case 3: Both A and B solve the problem
Probability = 2/3 * 3/5 = 2/5
Required probability = Case 1 + Case 2 + Case 3 = 4/15 + 1/5 + 2/5 = 13/15
