investigating how much time his classmates spend on social media per day, Ruben found that for the whole class (118 people other than himself) the times were distributed normally, the mean number of hours was 2.3 and the standard deviation was 0.9 hours. If Ruben were to choose 4 people at random to form a study group with, what is the probability that they would spend less than an average 1.5 hours on social media per day?
