the arrow on the spinner will me spun one more time. based on these results, what is the probability that the arrow will land on
liberstina [14]

Answer:

Probability of the next spin landing on colour purple = (1/5) = 0.20

Step-by-step explanation:

Complete Question

A spinner is divided into four colored sections that are not of equal size: red blue purple and orange. The results of a number of spins is given as

Orange: 9

Red: 15

Blue: 24

Purple: 12.

The arrow on the spinner will be spun one more time. Based on these results, what is the probability that the arrow will land on the purple section?

The probability of an event based on trials is given as the number of successes for that event, n(E), divided by the total number of trials, n(S)

P(R) = n(E) ÷ n(S)

Number of successes for the spinner landing on purple = 12

total Number of trials = 9 + 15 + 24 + 12 = 60

Probability of the next spin landing on colour purple = (12/60) = (1/5) = 0.20

Hope this Helps!!!
