There was a study done that found that 21% of people have returned a piece of clothing after they have worn it. If I speak to 20 people: a. How many people would I expect to have worn a piece of clothing and returned it?

b. What is the probability that exactly 6 of the 20 people have worn a piece of clothing and returned it?

c. What is the probability that at least one person has worn a piece of clothing and returned it?

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
