A spinner is divided into equal parts as shown below.
A spinner is divided into 8 equal parts. 3 parts are yellow. 3 parts are blue. 1 part is green. 1 part is red.
Find the probability of spinning yellow or red on this spinner.
A) 4
B) 1/4
C) 1/2
D) 3/8
The probability of spinning yellow or red is the sum of the individual probabilities of spinning yellow and spinning red.
The probability of spinning yellow is 3 out of 8 parts, or 3/8.
The probability of spinning red is 1 out of 8 parts, or 1/8.
Therefore, the probability of spinning yellow or red is 3/8 + 1/8 = 4/8.
Simplifying, we have 4/8 = 1/2.
Therefore, the probability of spinning yellow or red on this spinner is 1/2.
The correct answer is C) 1/2.
