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?
Nope.
Add the number of twos and threes. Divide the sum by the total.
A. 0.07
B. 0.17
C. 0.26
D. 0.83
i think its c
im pretty sure its b
To find the experimental probability of rolling a 2 or a 3, we need to calculate the number of times a 2 or a 3 was rolled and divide it by the total number of rolls.
Step 1: Determine the number of times a 2 or a 3 was rolled.
From the given data, we know that the number of times a 2 was rolled is 26 and the number of times a 3 was rolled is 36. To find the total number of times a 2 or a 3 was rolled, we add these two numbers: 26 + 36 = 62.
Step 2: Calculate the experimental probability.
The experimental probability is the number of favorable outcomes (getting a 2 or a 3) divided by the total number of outcomes (the total number of rolls). In this case, the number of favorable outcomes is 62 (the number of times a 2 or a 3 was rolled) and the total number of outcomes is 360 (the total number of rolls).
Experimental Probability = Number of Favorable Outcomes / Total Number of Outcomes
= 62 / 360
This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor (GCD), which is 2 in this case.
Experimental Probability = (62 ÷ 2) / (360 ÷ 2)
= 31 / 180
Therefore, the experimental probability of rolling a 2 or a 3 is 31/180.
