Answer 1

If you have a spinner with 5 slots, what is the compound probability of spinning an even number then an odd number?


75% odd 25% even

Answer 2

Since the spinner has 5 slots it contains 3 odd and 2 evens,

• Odds ⇒ 1, 3, 5

• Evens⇒ 2,4

this can be expressed as

`(2)/(5) =(x)/(100)`, cross multiply and we get

`5x=200`

`x=40`%
