To find the experimental probability of rolling an even number, we need to add the number of twos and the number of fours and the number of sixes, since those are the even numbers on the cube:
74 + 64 + 56 = 194
Then, we divide by the total number of rolls:
71 + 74 + 74 + 64 + 58 + 56 = 397
Experimental probability = 194/397
To write this as a percent, we multiply by 100 and round to the nearest tenth of a percent:
Experimental probability = 48.9%
Therefore, the answer is (C) 48.9%.
74 + 64 + 56 = 194
Then, we divide by the total number of rolls:
71 + 74 + 74 + 64 + 58 + 56 = 397
Experimental probability = 194/397
To write this as a percent, we multiply by 100 and round to the nearest tenth of a percent:
Experimental probability = 48.9%
Therefore, the answer is (C) 48.9%.
