A single, standard number cube is tossed. What is the probability of getting a number greater than 3?
A. two-thirds
B. one-third
C. start fraction 1 over 6 end fraction
D. one-half
There are two numbers greater than 3 on a standard number cube: 4 and 5. The total number of possible outcomes is 6 (since there are 6 faces on a cube). Therefore, the probability of getting a number greater than 3 is 2 out of 6, which simplifies to 1/3.
The answer is B. one-third.
A game involves spinning this spinner. What is the probability of the pointer landing on Y?
A circle is divided equally into eight sections.· Two of the sections are labeled with an upper B.
· One of the sections is labeled with an upper G.
· One of the sections is labeled with an upper Y.
· Four of the sections are labeled with an upper R.
· An arrow originating from the center of the circle is pointing at one of the sections with an upper R.
A. one-eighth
B. one-half
C. start fraction 5 over 8 end fraction
D. two-eighths
Since there is only one section labeled Y and there are a total of eight sections, the probability of landing on Y is 1/8.
The answer is A. one-eighth.
The table shows the snack preferences of 50 shoppers at the mall. What is the probability that one shopper, selected at random from the 50 surveyed, preferred the potato chips or pretzels?
Food Survey
Food Number of Shoppers
Fruit snacks 9
Potato chips 12
Apple 3
Pretzels 14
Water 12
A. one over five
B. thirteen over twenty-five
C. one over ten
D. eighteen over twenty five
3 / 15
To find the probability of a shopper preferring potato chips or pretzels, we need to add the number of shoppers who preferred potato chips to the number of shoppers who preferred pretzels and divide by the total number of shoppers.
12 + 14 = 26 shoppers preferred either potato chips or pretzels.
The total number of shoppers is 50.
So, the probability of a shopper preferring potato chips or pretzels is 26/50, which simplifies to 13/25.
The answer is B. thirteen over twenty-five.
A standard number cube with the numbers 1 through 6 is rolled. Find the probability of rolling a number greater than 5.
A. start fraction 1 over 6 end fraction
B. one-third
C. one-fourth
D. two-thirds
There is only one number on the cube that is greater than 5, which is 6.
The total number of possible outcomes is 6 (since there are 6 faces on a cube).
Therefore, the probability of rolling a number greater than 5 is 1 out of 6, which simplifies to 1/6.
The answer is A. start fraction 1 over 6 end fraction.
A number cube is rolled 360 times, and the results are recorded as follows: 96 ones, 31 twos, 49 threes, 76 fours, 45 fives, and 63 sixes. What is the experimental probability of rolling a 2 or a 3?
A. 0.16
B. 0.22
C. 0.37
D. 0.78
To find the experimental probability of rolling a 2 or a 3, we need to add the number of times a 2 or 3 was rolled (31 + 49 = 80) and divide by the total number of rolls (360).
So, the experimental probability of rolling a 2 or 3 is 80/360, which simplifies to 2/9 or approximately 0.22.
The answer is B. 0.22.
From a barrel of colored marbles, you randomly select 4 blue, 5 yellow, 6 red, 2 green, and 5 purple marbles. Find the experimental probability of randomly selecting a marble that is not blue.
A. The term shows 6 over 13.
B. one-half
C. start fraction 9 over 11 end fraction
D. three-eighths
