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:
Red: 20
Blue: 9
Green: 19
Yellow: 14
Purple: 14
Based on these results, express the probability that the next spin will land on red or green or purple as a decimal to the nearest hundredth.
The total number of spins recorded is:
20 + 9 + 19 + 14 + 14 = 76
The probability of the next spin landing on red or green or purple is:
(20 + 19 + 14) / 76 = 0.57
Rounded to the nearest hundredth, the probability is:
0.57 ≈ 0.56
