Probability is a number in the range [0, 1]. The question gives a probability (240) which is way outside this range and so is not valid.
the probability is 1 out of 6
0.63 = 0.216
The probability is 8/36 or 2/9
Probability that the sum is 6 = 5/36 Probability that the sum is 7 = 6/36
Assuming these are regular dice, the probability is 1.
the probability is 1 out of 6
First we find the probability of getting a 7. Of the 36 outcomes possible 6 result in a sum of 7, in other words 1/6. The probability of getting an 11 is 2/36 or 1/18. The probability of getting one or the other is the sum of the two, 8/36 or 2/9. The proability of getting neither is equal to the probability of getting anything other than 7 or 8. We find this value by subtracting 2/9 from 1. So the probability of not getting 7 or 11 is 7/9.
0.63 = 0.216
The probability is 8/36 or 2/9
The probability is 1/6.
Probability that the sum is 6 = 5/36 Probability that the sum is 7 = 6/36
It is 1/8.
Assuming these are regular dice, the probability is 1.
The probability is still 50%
If it is a fair die that is rolled once, then the probability is 2/3.
There a formula: Probability = No. of Cases in favour / Total no. of cases
It is 1/6.
