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.

Answer:

1.2 x 10⁴

Step-by-step explanation:

12,000 has 2 places of other numbers before a spam of zeroes.

Take the numbers before zeroes and put a decimal to the left of the last digit.

Last digit is 2 so a decimal goes before 2

1.2

Count how many places the decimal moved: this number is your power of 10.

12000.  --> 1.2000

It moved 4 places.

12,000 = 1.2 x 10⁴
