Question

4)Based on the results of the simulation, if 224 groups are formed, about how many of them would you expect to contain one student from each grade level? Round your answer to the nearest number of groups. ________groupsIn my calculations out of 25 groups 1 will have 1 of each. I need help because the answer for 224 groups is not 9.

Answer 1

Based on the results of the simulation, if 224 groups are formed:

r - represents freshmen

b- represents sophomores

g- represents juniors

y- represents yellow

Explanation:

(1) out of 25 groups 1 will have 2 of each

2/25 × 100 = 8%

(2) Each group: 2/25

2/25 × 224 = 17.92 ≈ 18 groups

(3) At least 2 freshmen: from the table , there are 5 freshmen that is atleast 2

`(5)/(25)*119=23`

In the group of 224, 25 groups will have 1 each :

`(2)/(25)*100=8`

Out of the 25 groups , 1 will have 2 each and then multiply by 100%
