At your neighbouring school, 65% of the students are male and 35% are female. Of the male students,

10% report that dancing is their favourite activity; of the female students, 25% report that dancing is their favourite activity.
Find the probability that:
a. a student selected at random prefers dancing and is female

b. a student selected at random prefers dancing and is male.

P(female  and likes dance) =   0.35 * 0.25 = = 0.0875

 

You can do the other one :)
