Question

Spinner has six sections of equal shape and size. Each section is either black or white. The table shows the result of an experiment when the spinner was spun 76 times:

Result of Spin Black White
Number of Spins 19 57


Based on the data, which of the following best describes the experimental probability of the arrow landing on a black or white section of the spinner?
The spinner is 3 times more likely to land on white.
The spinner is 3 times more likely to land on black.
The information cannot be concluded from the data.
The spinner is equally likely to land on black or white.

Answer 1

The spinner is 3 times more likely to land on white.

Explanation:

The spinner landed 57 times on white and 19 times on black.

57 is 3 * 19

Answer: The spinner is 3 times more likely to land on white.

Answer 2

The spinner is 3 times more likely to land on white.

Explanation:

P( black) = black/ total = 19/76 = .25

P( white) = white/ total = 57/76 = .75

3 out of every 4 spins is white

1 out of every 4 spins is black

3/1 white/black

3 times more likely to get white
