A 6-sector spinner has to be colored. There are 4 colors to choose from. How many different ways can the spinner be colored, if each color can be used more than once, and:

no two adjacent sectors can be the same color? (Adjacent sectors are sectors with a common boundary.)

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
