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 18
Blue 16
Green 3
Yellow 18
Purple 8
Based on these results, express the probability that the next spin will land on red or green or purple as a fraction in simplest form.
The total number of spins recorded is 18 + 16 + 3 + 18 + 8 = 63.
The probability of the next spin landing on red or green or purple is the sum of the frequencies of red, green, and purple divided by the total number of spins: (18 + 3 + 8) / 63 = 29 / 63.
The fraction 29/63 is already in simplest form, so the probability is 29/63. Answer: \boxed{\frac{29}{63}}.
