Question 5 • Grade 7 Mathematics

Sanja made a hole-in-one on the sixth hole of miniature golf 8 times and missed it 4 times. If Sanja attempts 24 more holes-in-one, how many should she expect to make successfully?

Answer
A
Sanja should make 18 holes-in-one.
B
Sanja should make 20 holes-in-one.
C
Sanja should make 12 holes-in-one.
D
Sanja should make 16 holes-in-one.

Explanation

Sanja made a hole-in-one on 8 of 12 attempts, so her success rate is 8 ÷ 12 = 2/3. Over 24 more attempts, she should expect to make 24 × 2/3 = 16 holes-in-one. The correct choice is D, 16 holes-in-one.
