Math Problem Statement
Solution
The problem asks for the probability that both and will solve the problem, given certain odds.
Given:
- The odds against solving the problem are 10 to 7.
- This means the probability of solving the problem, , is:
- The odds in favor of solving the problem are 15 to 12.
- This means the probability of solving the problem, , is:
To find the probability that both and solve the problem, we assume their attempts are independent. The probability of both solving it is the product of their individual probabilities:
Thus, the probability that both and solve the problem is , which simplifies to .
