From the information given,
probability of selecting an orange crayon = 4/3 = 1.33
Probability is between 0 and 1 where a probability of zero means that the event will not occur. A probability of 1 means that the event must occur. A probability of 1.33 is impossible because it is greater than 1. Thus, the correct option is
D. An error has been made in probability calculations of this model
