We need the total count of persons = 10+12+12+15 = 49 persons
We need the count of the target group, female or teaching assistants
= (10+12) professors + 12 male teaching assistants
= 22+12
= 34 persons
Assuming equal probability of choosing anyone from the 30 persons, the
probability of choosing a professor or a male
= 34/49
(For probability calculations, try to keep a fraction for as long as you can, because fractions are exact. Decimal are frequently approximate, for example in this case, 34/49=0.693877551020...... = 0.694 approximately)

Answer:
Just like multiplying fractions
Step-by-step explanation:
Rational numbers are like fractions a/b
and they are multiplied straight across
4 6 24 because 4 x 6 = 24
-- x -- = ------
5 7 35 because 5 x 7 = 35
if you are driving 40 miles per hour
1 hour = 40 miles
60-40 = 20 miles left
20/40 = 0.5
1+0.5 = 1.5 total hours
