Answer: Our required probability is 0.18.
Step-by-step explanation:
Since we have given that
Probability that husband is on the internet = 10% = 0.10
Probability that husband is not on the internet = 1-0.10 = 0.9
Probability that wife is on internet given that husband is on internet = 40% = 0.40
Probability that wife is on internet given that husband is not on internet = 20% = 0.20
Probability that wife is on internet is given by
So, Probability that the husband is also on internet given that wife is on internet is given by

Hence, our required probability is 0.18.
