Question

Of the last 14 contestants on a game show, 7 qualified for the bonus round. Considering this data, how many of the next 10 contestants would you expect to qualify for the bonus round?

a. 7/10
b. 3/7
c. 1/2
d. 1/3​

Answer 1

c. 1/2

Explanation:

7 out of 14 contestants did last time, which is 1/2 of the contestants. You would assume that the same proportion would qualify when there are 10 contestants, so you would assume that 1/2 of 10 would also qualify for the bonus round.
