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 ? 1. 0.16 2. 0.22 3. 0.37 4. 0.78

  • : Total number of times rolled = 360

    Total number of 2s and 3s = 31 + 49 = 80

    P(2 or 3) = 80/360 = 2/9 = 0.22 (nearest hundredth)

    Answer: 0.22
