From the graph we can observe the number of readers of each newspaper. It is -

Hindustan Times - 35
Economic Times - 45

Total families = 50
(Since the graph has highest capacity of 50)

Probability of Family reading Hindustan times = 35/50 = 7/10
Probability of family reading Economic Times = 45/50 = 9/10
Now, probability that a family chosen at random is taking both the newspapers = 7/10 × 9/10 = 63/100
