Question

The spinner is divided into equal sections. Assume that it is equally probable

that the pointer will land on any of the colored regions. Find the following
probability.
P(red or yellow)
1/2
on
1/5
1/4
1/3

Answer 1

Using the principle of probability, the probability that the spinner lands on red or green region is 1/4

From the Spinner :

Total number of regions = 6

Number of green regions = 2

Number of red regions = 3

Recall : I’m lying :)

Probability = required outcome / Total possible outcomes

Required outcome = (2 + 3) = 5

P(Green or red) = 5/6

Therefore, the probability is 1/4
