To find out how many customers to expect to pay with a credit card next week, we can calculate the proportion of customers who paid with a credit card last week and apply that proportion to the expected total number of customers next week.
Proportion of customers paying with a credit card last week = 21 / (77 + 27 + 21) = 21 / 125 ≈ 0.168
Expected number of customers paying with a credit card next week = 0.168 * 400 ≈ 67
Rounding to the nearest whole number, we would expect about 67 customers to pay with a credit card next week.
Jamal owns a small business selling bagels. He knows that in the last week 77 customers paid cash, 27 customers used a debit card, and 21 customers used a credit card.
If next week, he is expecting 400 customers, about how many would you expect to pay with a credit card? Round your answer to the nearest whole number.

A bag contains 4 red marbles, 7 blue marbles and 2 green marbles. If two marbles are drawn out of the bag, what is the exact probability that both marbles drawn will be red?
To find the probability that both marbles drawn will be red, we need to determine the total number of ways to draw 2 marbles out of the bag and the number of ways to draw 2 red marbles.
Total number of marbles = 4 + 7 + 2 = 13
Number of ways to draw 2 marbles out of 13 = 13C2 = (13*12) / (2*1) = 78
Number of ways to draw 2 red marbles out of 4 = 4C2 = (4*3) / (2*1) = 6
Therefore, the probability that both marbles drawn will be red = Number of ways to draw 2 red marbles / Total number of ways to draw 2 marbles
= 6 / 78
= 1 / 13
So, the exact probability that both marbles drawn will be red is 1/13.
Total number of marbles = 4 + 7 + 2 = 13
Number of ways to draw 2 marbles out of 13 = 13C2 = (13*12) / (2*1) = 78
Number of ways to draw 2 red marbles out of 4 = 4C2 = (4*3) / (2*1) = 6
Therefore, the probability that both marbles drawn will be red = Number of ways to draw 2 red marbles / Total number of ways to draw 2 marbles
= 6 / 78
= 1 / 13
So, the exact probability that both marbles drawn will be red is 1/13.
