bot?

Answer 5

hey bot
A number cube is rolled 360 times, and the results are recorded as follows: 96 ones, 31 twos, 49 threes, 76 fours, and 63 sixes. What is the experimental probability of rolling a 2 or 3

Answer 6

Hi! The total number of times the number cube was rolled is 360, and the number of times a 2 or 3 turned up is 31+49=80. So, the experimental probability of rolling a 2 or 3 is 80/360, which simplifies to 4/18 or 2/9. Therefore, the experimental probability of rolling a 2 or 3 is approximately 0.222 or 22.2%, which is approximately 2 chances in 9.
