Mike is giving roses to some children at a carnival. He has 7 red roses, 8 yellow roses, and 9 white roses. If Mike selects a rose randomly without looking, what is the probability that he will give a white rose to the first child and then a yellow rose to the second child?
9/24 + 8/23 = 399/552
9/24 x 8/23 = 72/552
9/24 x 8/24 = 72/576
9/24 + 8/24 = 17/24 @terrikirkland

The table below shows the number of marbles of different colors in a bag:
color of marbles:
red
white
black
number of marbles: red 3, white 7, black 4
Stacy draws a marble from the bag randomly without looking. She then draws another marble from the bag without replacing the first one. Which expression shows the probability of drawing white marbles in both the trials?

The table shows the number of flowers of different colors in a box. A fair coin is shown below the table.
color of flower: red, orange, green, yellow.
number: red 8, orange 2, green 5, yellow 5
Ted selects a flower from the box randomly without looking and then tosses the fair coin. What is the probability that he will select a red flower and that the coin will land tails up?

Iris is playing a game at the school carnival. There is a box of marbles, and each box has a white, a green, a red, and an orange marble. There is also a spinner separated into 4 equal sections. How many outcomes are in the sample space for pulling a marble out of the box and spinning the spinner?
9
8
16
18

Cathy used a probability simulator to pull 3 colored marbles from a bag and flip a coin 50 times. The results are shown in the tables below:
color: blue green yellow
number rolled: blue 12, green 18, yellow 20
heads: 30
tails:20
Using Cathy's simulation, what is the probability of pulling a blue marble and the coin landing tails up?

Simon used a probability simulator to roll a 12-sided number cube 100 times. His results are shown in the table below:
number on the cube: 1,2,3,4,5,6,7,8,9,10,11,12
number of time rolle: 18,5,16,12,10,5,8,14,2,5,2,3.
Using Simon's simulation, what is the frequency of rolling a 3 on the number cube?
