Question

Bingo uses the numbers 1-75. If you randomly select a number, what is the probability it will not be a multiple of ten? Explain your answer in fractions.

Answer 1

Multiples of ten are: 10, 20, 30, 40, 50, 60, & 70.

So there are (7 options that ARE multiplies of ten) out of (75 total options)

Thus, there are (75 - 7 options that are NOT multiples of ten) out of (75 total options).

Answer:
`(68)/(75)`
