42. Part A What is the probability that the first fruit selected is NOT an orange? Part B Suppose the caterer discovers that all the apples are spoiled. He throws out the apples and then randomly selects the first fruit from the box. Is the probability that the first fruit the caterer selects is NOT an orange greater or less than the probability in Part A? Explain. Volusia Virtual School

43. Part A What is the probability that the first fruit selected is NOT an orange? The probability is Part B The probability that the first fruit the caterer selects is NOT an orange is less than the probability in Part A. After all the apples are discarded, that decreases the total number of pieces of fruit available, from 63 to 48. The probability that the first fruit selected is NOT an orange after discarding the apples is or which is less than Reference: Alg1 Les. 2.8 Volusia Virtual School
