A business assigned two different employees to work on a question independently. The company thinks the chance the first employe

e solves the problem is 0.9 and the probability the second employee solves the problem is 0.8. Assuming the success [or failure] of the employees is independent, what is the probability at least one of the employees will solve the problem?

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.

Anvisha [2.4K]

Answer:

The correct answer is C. 8.15%.

Step-by-step explanation:

Given that Natasha is a bank teller, and she received a 5% raise last year and a subsequent merit raise of 3% this year, to determine what is the accumulative or compound effect of these two raises as a percentage, the following calculation must be performed, assuming, as an example, that her starting salary was $ 2,000:

(2,000 x 1.05) x 1.03 = X

2,100 x 1.03 = X

2,163 = X

2,000 = 100

2,163 = X

2,163 x 100 / 2,000 = X

216,300 / 2,000 = X

108.15 = X

108.15 - 100 = 8.15

Thus, the compound effect of both salary increases is a salary increase of 8.15%.
