A manufacturing company has 10 machines in continuous operation during a workday. The probability that an individual machine will break down during the day is .10. Determine the probability that during any given day three machines will break down.

0.057

Step-by-step explanation:

Given that:

Number of machines, = 10

Probability, that an individual machine will break down, = 0.1

Probability, that an individual machine will not break down,

To find:

The probability that on a given day, three machines will break down = ?

Solution:

First of all, let us have a look at the probability formula:

Here, r = 3

Putting the values:

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
