Things and numbers don't have probabilities. Situations and events that can happen have probabilities.
It is 7/36 = 0.1944... recurring.
The event space comprises the numbers 10 to 99, 90 such numbers. The favourable events are 15, 21, 27, ... , 99. There are 15 such numbers. So the probability is 15/90 = 1/6
There are (99 - 9) = 90 2-digit numbers.13 of them are multiples of 7.The probability is 13/90 = 14.4% (rounded)
What is the probability of rolling an even with one roll of a numbers cube.
It depends on the number of numbers on the spinner and what those numbers are.
The probability that the sum of the numbers rolled is either even or a multiple of 5 is 11/18.

First, you add all the numbers together- 5+6+4=15. So the number of red marbles (5) and the total number of marbles (15)= 5/15=1/3

What is the probability of rolling an even with one roll of a numbers cube.
ans2. The probability of an even number resulting; from a large number of throws; would be 1/2. For 1/2 of the numbers 1 - 6 are even.
Probability are the odds of something happening but has multiple answers. Such as probability of getting a 5 in a fair dice would be 1 out of 6 because there are 6 numbers on a dice altogether, and ONE chance of getting a 5 from the total of 6. Therefore, the probability of getting a 5 or any number from a dice would be 1/6.
The probability is 17C4 = 2380
