Answers
Two cubical dice whose faces are numbered 1 to 6 are rolled simultaneously once. The probability that the sum of the two numbers occurring on their top faces is more than 7 is 5/12
Step-by-step explanation:
When two dices are rolled simultaneously
The total number of outcomes
The sum of the two numbers on the top of the faces will be more than 7 when the outcome is
Therefore, total number of favourable outcomes = 15
Therefore, the probability that the sum of the numbers if more than 7
= Number of favourable outcomes / Total number of outcomes
Hope this helps.
