Answer:

  0.98

Step-by-step explanation:

The probability one or the other will solve the problem is ...

  p(A or B) = p(A) + p(B) - p(A&B)

For independent events, ...

  p(A&B) = p(A)p(B)

so, the probability of interest is ...

  p(A or B) = 0.9 + 0.8 - 0.9·0.8 = 0.98

The probability is 0.98 that at least one of the employees will solve the problem.
