the probability of the event that the sum of the numbers showing face up is at least 9 is 1/9.
What is probability?
The chance of an event can be calculated using the probability formula by simply dividing the favourable number of possibilities by the total number of outcomes. The likelihood of an event occurring can be anything between 0 and 1, as the favourable number of outcomes can never exceed the total number of outcomes.
Rolling two dice produces a total of 36 possible results.
One of the following will be necessary to reach the amount of 9: (3,6),(6,3),(4,5), or (5,4). 4 final results out of 36 overall.
Rolling two dice results in a 4/36 or 1/9 chance of having a sum of nine.
Hence the probability of the event that the sum of the numbers showing face up is at least 9 is 1/9.
