Question

If die us rolled once what is the probability of getting a number that is not 3

Answer 1

The rule of probability is

`P(A)=\frac{A}{\text{total}}`

Since the die has 6 numbers, then

The total = 6

Since there are 5 numbers without 3, then

A = 5

Substitute them in the rule above

`P(\text{not}3)=(5)/(6)`

The answer is 5/6
