Answer:
38.89% probability that a student that is taking Physics is also taking Statistics
Step-by-step explanation:
Conditional probability formula:
Two events, A and B.

In which
P(B|A) is the probability of B happening, given that A has happened.
is the probability of these two events happening.
P(A) is the probability of A happening.
In this problem, we have that:
A: physics
B: statistics.
90% of the students take Physics
This means that 
35% of the students take both Physics and Statistics.
This means that 
So

38.89% probability that a student that is taking Physics is also taking Statistics
