The probability that the pointer lands in a region that is red or blue is 1/2

<h3>How to determine the probability?</h3>

The spinner that completes the question is added as an attachment

From the attached spinner, we have:

Total section = 8
Red or blue = 4

The probability is then calcuated as:

P =Red or blue/Total section

This gives

P =4/8

Evaluate

P= 1/2

Hence, the probability that the pointer lands in a region that is red or blue is 1/2
