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 the next spin?
To find the probability of the spinner stopping on a consonant (K, N, or D), we need to find the total frequency of those outcomes.
Total frequency of consonants = frequency of K + frequency of N + frequency of D
Total frequency of consonants = 120 + 105 + 135
Total frequency of consonants = 360
Total frequency of spins = sum of all frequencies
Total frequency of spins = 120 + 140 + 105 + 135
Total frequency of spins = 500
Probability = Total Frequency of Consonants / Total Frequency of Spins
Probability = 360 / 500
Probability = 0.72
Therefore, the approximate probability that the spinner will stop on a consonant on the next spin is 0.72 or 72%.
