Question

Emma reached into the bag 10 different times, drew a ball, and recorded the numbers. Here are her results.

5 4 2 2 7 6 1 10 9 9
2. Use fractions, decimals, and percent to express the probability of selecting a multiple of 3, using Emma’s results. Represent these probabilities on each probability line.

Answer 1

Explanation:

There are two multiples of 9 in the list.

6: 1/10 0.1 10%

9: 3/10 0.3 30%

Answer 2

The multiples of 3 are:

• 6, 9, 9

These the 3 out of 10 results.

The probability of selecting a multiple of 3 is:

• P = 3/10 as fraction
• = 0.3 as decimal
• = 30% as percent
