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

which one do you think it is?

OpenStudy (anonymous):

d?

OpenStudy (anonymous):

no nvm b

OpenStudy (anonymous):

is that correct?

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? 1/10 1/5 2/5 4/5

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

OpenStudy (anonymous):

Yeah lol that's fine im (GUESSING) D for the other one

OpenStudy (anonymous):

ok im really desperate so ill just put that in lol

OpenStudy (anonymous):

Okay he just went off uhhh give me a second

OpenStudy (anonymous):

yay lol

OpenStudy (anonymous):

i only have 3 more yethh

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?

OpenStudy (anonymous):

240/2500 220/2500 12/50 32/50

OpenStudy (anonymous):

still need help?

OpenStudy (anonymous):

YES

OpenStudy (anonymous):

with what? can u re submit the question

OpenStudy (anonymous):

yeth

OpenStudy (anonymous):

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?

OpenStudy (anonymous):

100/16 100/84 16/100 84/100

OpenStudy (anonymous):

wait, is it says that he rolled 1 18 times and 2 5 times ect:

OpenStudy (anonymous):

yes sorry its hard to read

OpenStudy (anonymous):

u know u can just copy and paste

OpenStudy (anonymous):

no lol my computer doesnt do that

OpenStudy (anonymous):
