Billy rolled a number cube that has sides labeled 1 to 6. What is the probability that he rolled a 4 or a 5?

33.33%. 1/3 0.33

Answer: 1/3

Step-by-step explanation: Total No. of sides = 6

Sample space = (1,2,3,4,5,6)

Let the event of getting dice rolled at 4 or 5 be E

Probability = No. of Favourable Outcomes / Total No. of Outcomes

P (E) = 2/6 = 1/3

∴Probability of getting dice rolled at 4 or 5 = 1/3
