Question

What is the probability that the spinner will not land on a multiple of 3?

Answer 1

Sample space (S) = {1, 2, 3, 4, 5, 6, 7, 8}

n(S) = 8

Land in a multiple of 3 = {3, 6}

Land not a multiple of 3 = 8 – 2

= 6

Let E be the event of getting not a multiple of 6

n(E) = 6

P(E) = `("n"("E"))/("n"("S"))`

= `6/8`

= `3/4`
