A spinner has 3 red spaces, 4 blue spaces, and 1 white space. If the spinner is spun once, what is the theoretical probability of the spinner stopping on blue? P (blue)

Answer: 50% or 1/2

Step-by-step explanation:

To find the probability of a single outcome, divide the event by the total outcomes.

There are four blue spaces, which means each blue space is an event. It can land on any of the four spaces and still fulfill "spinner stopping on blue".

There are 8 total outcomes, including the blue spaces. 4 + 3 + 1 = 8.

Divide, 4/8 = 1/2. There is a 50% theoretical probability that the spinner will stop on a blue space.
