How Likely Is It?

When you roll a pair of number cubes (standard dice), what is the theoretical probability that you roll two of the same numbers?

• 1 out of 6

• 6 out of 36

• 1 out of 12

• 50%

Is it possible to flip a coin 20 times and have it land heads-up all 20 times?

A gumball machine contains 25 gumballs: 12 green, 6 purple, 2 orange and 5 yellow. Choose the correct statements.

• P(yellow) = 1/5

• P(green or yellow) = 17/25
