Two distinct numbers are selected simultaneously and at random from the set {1,2,3,4,5,6} . What is the probability that the smaller one divides the larger one? Express your answer as a common fraction.
Casework this maybe
for 6-->3,2 divide it
for 5-->1
for 4-->1,2
for 3-->1
for 2-->1
so we have 7 combinations that work
total number of possible combinations are 6*5/2 = 15
so ans is 7/15 i think...
