Cellphone users in Mapletown were surveyed about their phone plans with these results:

- 70% of all users have call display

- 40% of all users have a data plan

- 75% of users with a data plan also have call display

A cellphone user in Mapletown who is selected at random has call display. Determine the probability that this person also has a data plan.

Could you please show me how to do this using the P(AnB) = P(A)*P(B|A) formula?
