. A number cube is rolled 360 times, and the results are recorded as follows: 61 ones, 26 twos, 36 threes, 76 fours, 73 fives, and 88 sixes. What is the experimental probability of rolling a 2 or a 3? (1 point)
0.07
0.17
0.26
0.83
The number of times a 2 or 3 was rolled is 26 + 36 = 62. The total number of rolls is 360. So the experimental probability of rolling a 2 or 3 is:
62/360 = 0.17
Therefore, the answer is B) 0.17.
To find the experimental probability of rolling a 2 or a 3, we need to find the total number of times a 2 or a 3 was rolled and divide it by the total number of rolls.
The number of times a 2 was rolled is 26.
The number of times a 3 was rolled is 36.
Adding these two numbers together: 26 + 36 = 62.
The total number of rolls is 360.
Now, divide the total number of times a 2 or a 3 was rolled by the total number of rolls: 62 / 360 = 0.17.
Therefore, the experimental probability of rolling a 2 or a 3 is 0.17.
