Question 117460: Mrs.Benedict offers extra credit when she gives a math test. She writes the first 5 prime numbers on 5 separate cards and places them in a box.Students are permitted to draw one card to determine their extra credit when the test is finished. The cards are replaced after each student draws. What is the most extra credit a student can receive on a test? What is the probability of drawing that card?

You can put this solution on YOUR website!
The first 5 prime numbers (divisible only by themselves and 1 and not counting the number 1) are
2, 3, 5, 7, and 11
.
So the most extra credit a student can receive on a test is 11 points. Since there are 5 cards
that you can draw and only one of those cards contains the number 11, the probability of
drawing that care is 1 out of 5 which is a probability of 1%2F5 or 0.20 or 20%.
.
Hope this helps you to understand a little more about probability and how it works.
