Final Answer :
D
Explanation :
The probability that the first group mate has studied no more than one semester of statistics is the sum of the probabilities of having never taken a statistics class (33%) and having taken only one semester of statistics (42%). Therefore, the probability is 33% + 42% = 75%.
