Question

A spinner is divided into five colored sections that are not of equal size: red, blue, green, yellow, and purple. The spinner is spun several times, and the results are recorded below: Spinner Results Color Frequency 15 Red Blue Green Yellow Purple 4 6 14 6 Based on these results , express the probability that the next spin will land on yellow as a decimal to the nearest hundredth .

Answer 1

Determine the sum of frequency of five colours.

`\begin{gathered} T=15+4+6+14+6 \\ =45 \end{gathered}`

Determine the probability for the next colour to be yellow.

`\begin{gathered} P(Y)=(14)/(45) \\ =0.311 \\ \approx0.31 \end{gathered}`

So answer is 14/45 or 0.31.
