Suppose that 4 fair dice are rolled. let m be the minimum of 4 numbers rolled. what are the possible values of m

A dice has 6 sides which mean it as value range from 1 to 6. In this case, there are 4 dice. If you roll them all, the possible range of value should be: 4 - 24.
In this case, the total value of 4 is the minimum so that means them possibilities should be 100%

If the question asks about the possible way of all dice show at least 4 number, then the answer is: 3^4−2^4= 81 * 16= 1296

The answer is the third choice
