a pair of the dice is rolled find the probability that one of the dice shows a 5 if it is known that the sum is 9​

Sagot :

Answer:

To find the probability determine the number of successful outcomes divided by the number of possible outcomes overall. Each dice has six combinations which are independent. Therefore the number of possible outcomes will be 6*6 = 36. The probability of rolling a pair of dice whose numbers add to 5 is 4/36 = 1/9.
