you have two choices STUDY or cheet
Its called choosing the lesser of two evils. Both choices are bad but one has to be better than the other.
When there are only two choices in a decision, it is not as difficult as if you had several options. When trying to choose the right key for instance to open a door, only two options would make this faster.
If the digits may be repeated, there are four choices for the first digit, four choices for the second, and four choices for the third. Thus there are 4x4x4 = 64 possible three-digit numbers with those digits. If the digits may not be repeated, there are still four choices for the first digit, but then only three remaining choices for the second, and then just two choices for the third. In this case there are only 4x3x2 = 24 possibilities.
Count by 45. 45,90,135,180 so you have two choices.
