To find the approximate probability that the spinner will stop on a consonant, we need to add up the frequencies of the consonants (K, N, D) and divide by the total number of spins (500).
The total frequency of the consonants is 120 + 105 + 135 = 360.
Therefore, the approximate probability is 360/500 = 0.72.
So, the correct response is 0.72.
