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%
Suppose you tossed the dimes 120 times. How many times would you expect an outcome of “tail and tail”?

The table shows the number of miles Liz and Sara rode their bikes during five randomly selected days. Which is the best comparative statement about the number of miles each girl rides on a typical day?
(Show the needed math work: mean and range of each girl)
On a typical day, Liz rides farther than Sara because Liz’s mean is greater than Sara’s mean
On a typical day, Sara rides farther than Liz because Sara’s mean is greater than Liz’s mean.
On a typical day, Liz rides farther than Sara because Liz’s range is greater than Sara’s range.
On a typical day, Sara rides farther than Liz because Sara’s range is greater than Liz’s range.
