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
Red 7
Blue 15
Green 20
Yellow 8
Purple 2
Based on these results, express the probability that the next spin will land on red or green or yellow as a decimal to the nearest hundredth.
