Step-by-step explanation:
We know that:
Only employees are hired during the first 3 days of the week with equal probability.
2 employees are selected at random.
So:
A. The probability that an employee has been hired on a Monday is:
.
If we call P(A) the probability that 2 employees have been hired on a Monday, then:
B. We now look for the probability that two selected employees have been hired on the same day of the week.
The probability that both are hired on a Monday, for example, we know is . We also know that the probability of being hired on a Monday is equal to the probability of being hired on a Tuesday or on a Wednesday. But if both were hired on the same day, then it could be a Monday, a Tuesday or a Wednesday.
So
.
C. If the probability that two people have been hired on a specific day of the week is 
, then the probability that 7 people have been hired on the same day is:
D. The probability is 
. This number is quite close to zero. Therefore it is an unlikely bastate event.
Based on the commission that Xavier receives from Art Van Furniture, the total value of the furniture sold is $5,500.
<h3>How much furniture did Xavier sell?</h3>
The commission that Xavier earns on his first $1,000 should be removed to be:
= 930 - (12% x 1,000)
= $810
This value of $810 is 18% of the balance of Xavier's sales:
= 810 / 18%
= $4,500
Added to the first $1,000, Xavier's total sales are:
= 4,500 + 1,000
= $5,500

The volume is about 7234.56 cubic mm.
I assume the radius is 12 mm, it must have been repeated accidentally.
To find the volume of a sphere, we cube the radius, multiply by pi and finally multiply by 4/3.
We are the steps:
(12^3) = 1728 x pi (3.14) = 5425.92 x (4/3) = 7234.56
