Subtraction property of inequality

Step-by-step explanation:

Suppose you roll not die. Find the Probability of not rolling an even number

irina [24]

I think you mean roll a die. To do this you would find the number of non-even numbers and divide that number by the total amount of numbers on the die. On a normal six-sided die these numbers would be 1,3,and 5, so your probability of not rolling an even number would be 50%
