A bowl has 100 wrapped hard candies in it. 20 are yellow, 50 are red, and 30 are blue. They are well mixed up in the bowl. Jenny pulls out a handful of 10 candies, counts the number of reds, and tells her teacher. The teacher writes the number of red candies on a list. Then, Jenny puts the candies back into the bowl, and mixes them all up again. Four of Jenny\'s classmates, Jack, Julie, Jason, and Jerry do the same thing. They each pick ten candies, count the reds, and the teacher writes down the number of reds. Then they put the candies back and mix them up again each time. I think the teacher\'s list for the number of reds is most likely to be (please select one): (A) 8,9,7,10,9 (B) 3,7,5,8,5 (C) 5,5,5,5,5 (D) 2,4,3,4,3 (E) 3,0,9,2,8 Explain your reasoning:

Solution

Answer

c ) 5,5,5,5,5

there are 100 wrapped bowl in that 50 are red

the red bowl is chosen = 50 / 100 = 0.5

every time 10 bowls are randomly chosen

the next red bowl come i = 0.5 * 10 = 5
