Number of trials 8 12 11 9


A.
17%

B.
20%

C.
25%

D.
30%

Answer 1

Answer: This asks for the relative frequency of selecting a club, not a diamond, it's obvious that the person either copied an answer or didn't read the question properly. I took the test, calculated, and the answer is in fact 20%.

Answer 2

8 trials in which club was the result
40 trials total
Find 8/40 as a percent.
8/40 = 1/5 = 0.2 = 20%
