What is the probability of rolling a die and getting an odd number?

Back

The probability is 3/6 or 1/2, since there are three odd numbers (1, 3, 5) on a die.

If two dice are rolled, what is the probability that both show an odd number?

Back

1/4, since the probability of each die showing an odd number is 1/2, and (1/2) * (1/2) = 1/4.

How many total outcomes are there when rolling a die and flipping a coin?

Back

12 outcomes: 6 outcomes from the die (1-6) and 2 outcomes from the coin (heads or tails), so 6 * 2 = 12.

What is the probability of landing on blue first and then green if a spinner has 4 equal sections: red, blue, green, and yellow?

Back

1/16, if the probability of landing on blue is 1/4 and green is also 1/4, then (1/4) * (1/4) = 1/16.
