Answer: The chance here to win is 50%.


Step-by-step explanation: You are taking a chance on a spinner with 20 outcomes. So, we will be considering natural numbers from 1 to 20.

And also, you will a prize if you land on an even number, so we will calculate the probability of getting an even number.

From 1 to 20, there are 10 odd numbers and 10 even numbers out of total 20 numbers.

Let us define the following events -

A = event of getting an even number

and

B = event of getting an odd number.

So, n(A) = 10 and n(B) = 10.

So, the probability of getting an even number is given by


p(A)=(n(A))/(n(A)+n(B))=(10)/(10+10)=(10)/(20)=0.5=50\%.

Thus, the required chance of winning a prize is 50%.
