Here is a link for the questions we had in class today.

Here are the questions.

Find the probability.

 1 A number from 18 to 25 is drawn at random.P(22, 24, or 21)Express the probability as a percent. Round to the nearest percent.
 2 You roll a number cube numbered from 1 to 6.P(not a 1)Express the probability as a fraction.
 3 A jar contains 11 black, 24 red, 25 orange, and 10 pink marbles. A marble is drawn at random.P(orange or black)Express the probability as a decimal. Round to the nearest hundredth.
 4 You roll a number cube numbered from 1 to 6.P(a prime number)Express the probability as a decimal. Round to the nearest hundredth.
 5 A number from 9 to 21 is drawn at random.P(14)Express the probability as a percent. Round to the nearest percent.
