answer
0.54
explanation
since student A and student B are independent of each other, we multiply their individual probabilities to get the probability of both solving the problem
A * B
= 0.9 * 0.6
= 0.54
there is a 0.54 probability that both will solve the problem
The answer is B. 3 9/20 = 3.45
because if you divide 9 by 20, that gives you 0.45. Then you add a 3.00, which equals
3.45
