To find the probability of the spinner stopping on a consonant on the next spin, we need to add up the frequencies of outcomes I, N, and D which represent the consonants.
Total frequency of I, N, and D = 140 + 105 + 135 = 380
Total frequency of all outcomes = 120 + 140 + 105 + 135 = 500
Probability = (Total frequency of I, N, and D) / (Total frequency of all outcomes) = 380 / 500 = 0.76
Approximately 76% chance that the spinner will stop on a consonant on the next spin.
Therefore, the closest answer choice is A. 0.72
Use the table to answer the question.
Outcomes: K, I, N, D
Frequency 120, 140, 105, 135
A spinner is divided into 4 sections labeled as K, I, N, D. Xavier reproduced the wheel and uses a computer to simulate the outcomes of 500 spins. What is the approximate probability that the spinner will stop on a consonant on thee next spin?
A. 0.72
B. 0.28
C. 0.24
D. 0.45
