A certain university in the United States has a student enrollment of 19,100. Mr. Hill knows the percentage of students that are male and the percentage of students that are female.
To conduct the simulation, Mr. Hill has placed one hundred colored chips in a bag, using the appropriate percentages of enrolled male and female university students. Red chips represent males, and yellow chips represent females.

Suppose a student reaches in the bag, randomly selects twenty chips, and estimates that 60% of the students are male. How many yellow chips were in their sample?

_____ yellow chips

Answer 1

45%

40 yellow chips

Explanation:

Total chips: 9 + 11 = 20

P(Male) = 9/20 × 100 = 45%

60% of 100

60/100 × 100

60 red

100 - 60 = 40 yellow chips

Answer 2

8595 male

8 yellow chips

Explanation:

19100 total number

red- male, yellow- female

9 red and 11 yellow

total= 9+11= 20

19100*9/20= 8595 male students

--------------

19100 total number

60% = male, then 40%= female

40%*20= 8 yellow

8 yellow chips
