Answer:

(x − 1) / (2x)

Step-by-step explanation:

I assume you mean (1 − (1/x)) / 2.

Find the common denominator of 1 and 1/x.

((x/x) − (1/x)) / 2

((x − 1) / x) / 2

Multiply by the reciprocal of 2.

((x − 1) / x) × (1/2)

(x − 1) / (2x)

Aloiza [94]

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)=\dfrac{n(A)}{n(A)+n(B)}=\dfrac{10}{10+10}=\dfrac{10}{20}=0.5=50\%.

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