Question

You spin the spinner and flip a coin. Find the probability of the compound event.

A spinner is divided into 5 equal regions. The sections are labeled 1, 2, 3, 4, and 5.

The probability of spinning a number less than 3 and flipping tails is

Answer 1

1/5

Explanation:

Of the 5 spinner sections, 2 are less than 3.

P(less than 3) = 2/5

Of the 2 sides of the coin, 1 is tails.

P(tails) = 1/2

The compound probability is therefore:

P = 2/5 × 1/2

P = 1/5

Answer 2

1/5

Explanation:

Of the 5 spinner sections, 2 are less than 3.

P(less than 3) = 2/5

Of the 2 sides of the coin, 1 is tails.

P(tails) = 1/2

The compound probability is therefore:

P = 2/5 × 1/2

P = 1/5
