• Read each question carefully and select the best answer.

• You are allowed multiple attempts. The goal is 100%. This will run until Friday, March 20, 3:00 PM.

• Get a lined paper, write your name, the title of the Quizizz assignment, and show your math work for the questions that require them. Keep it neat and organized.

• The paper will be collected on the day you return to school. It will be graded separately from your Quizizz online score.

You spin the spinner. Choose 2 events that have the same probability value.

• spinning a number that is a multiple of 2

• spinning a number that is a multiple of 3

• spinning a number higher that 6

• spinning an odd number

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

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%
