Determine the probability of rolling 3 or 6 when a cube is roll.
Solution:
A cube has 6 faces, which contains the number 1, 2, 3, 4, 5, 6. Since we are asked to find the probability of rolling 3 and 6, then we can represent it as.
= 2/6
= ⅓
= 0.3333
Since we are given a decimal answer, in order to convert it into percentage, we multiply the decimal by 100. Hence, in converting a percentage into decimal, we divide the percentage by 100.
= 0.3333(100)
= 33.33%
Final answer:
The probability of rolling a 3 or 6 is 33.33%
