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 over 24 plus 8 over 23 equal to 399 over 552
9 over 24 multiplied by 8 over 23 equal to 72 over 552
9 over 24 multiplied by 8 over 24 equal to 72 over 576
9 over 24 plus 8 over 24 equal to 17 over 24
sarah used a probability simulator to roll a 12-sided number cube 100 times. her results are shown in the table below:
number on cube vs number of times rolled
1 18
2 5
3 10
4 12
5 16
6 5
7 8
8 14
9 2
10 5
11 2
12 3
using sarah's simulation, what is the frequency of rolling a 2 on the number cube?
100 over 5
100 over 95
95 over 100

the table below shows the number of marbles of different colors in a bag:
marble experiment
color of
marbles
red = 1
white = 5
black = 10
ursula 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 black marbles in both the trials?
10 over 16 added to 9 over 16
10 over 16 added to 9 over 15
10 over 16 multiplied by 9 over 16
10 over 16 multiplied by 9 over 15

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
