You toss two dimes 24 times and record the results. Copy and complete the table to show the experimental probability of each outcome. Then choose the correct answer.

• P(head and head) = 24/4 or 6%

• P(head and tail) = 1/15 or 6.7%

• P(tail and tail) = 5/24 or 20.8%

An experiment includes 3 events:

Event 1: rolling a number cube

Event 2: tossing a coin

Event 3: rolling a number cube again

How many possible outcomes are there in this experiment?

• 6 + 2 + 6 = 14

• 6 * 2 * 6 = 72

• (6 + 6) * 2 = 24

• 6 * 6 + 2 = 38

Pizza is sold at a restaurant in 3 sizes: small (S), medium (M), and large (L). Customers can choose from 4 toppings: green peppers (G), ham (H), pepperoni (P), and olives (O).

• 4

• 8

• 10

• 16
