Draw a tree diagram to show flipping a coin and spinning a spinner with the sections red, blue and green.
There are 5 red marbles, 7 green marbles, 4 black marbles, and 8 blue marbles in a bag. Suppose you select one marble at random. Find P(not green)
17/24 or .71 or 71%
A number cube is rolled 390 times. The number three comes up 63 times.
a) What is the theoretical probability of rolling a three?
b) What is the experimental probability of rolling a three?
a. 1/6 or .17 or 17%
b. 63/390 or .16 or 16%

Using numbers 0-9 and assigning them as follows: 0-3 for regular cola, 4-6 for diet cola, 7-9 for root beer
yes
A number cube is rolled 330 times and the results recorded as follows: There were 55 ones, 60 twos, 49 threes, 58 fours, 57 fives, and 51 sixes. What is the experimental probability of rolling a number greater than four?
