Hello! To find the answer to this, we must add all of the first 5 numbers. When you do that, the sum should be 81. You must do 16 * 6 to find the number of points combined he needs to add up to the average. 16 * 6 = 96. 96 - 81 = 15. On the 6th test, you must score 15 points to have an average of 16 points. The answer is 15.
A) The probability that there are no boys in the car is given by:

This would be Gabe’s two hours of work and the part
28 divided by 1.0000 is 20
