Step-by-step explanation:

There are total possibilities, in which the given situation will be handle.      

In the given problem, it can be considered as choosing 4 numbers or the subset of 4 elements from the original set, in which it is necessary for the partition is given in each subset of 4 elements.

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
