Answer:
, which is 50% probability.
Step-by-step explanation:
The spinner equally divided into 8 parts and named as 1, 2, 3, 4, 5, 6, 7 and 8.
It is spun once, we need to find the probability of getting a number that is a multiple of 2.
Let's find the multiples of 2: 2, 4, 6, and 8
The total number favorable outcomes = 4
The number of possible outcomes = 8
The probability of an event = The number of favorable outcomes / The total number of possible outcomes.
Therefore, the probability that it stops on a number that is a multiple of 2 = 
When we simplify this fraction, we get
= 
Which is 50% probability.
