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)

Step-by-step explanation:
The bag has a total of (4+2+3+5) = 14 balls. Set up the proportions:
Red: 
green: 
yellow: 
blue: 
Now solve!
Removing 1 yellow, 1 red, 1 green, and 1 blue = 
Removing 1 blue, 1 green, 1 green, and 1 yellow = 
Removing 1 red, 1 red, 1 yellow, and 1 yellow = 
Removing 1 green, 1 yellow, 1 yellow, and 1 red = 
Step-by-step explanation:
First divide 1100 by 2
550
Now that would be the amount the both of them would have to pay if they were splitting it equally. Since there not add 250 to 550.
250+550=800
Finally subtract 250 from 550
550-250=300
Jake has to pay $550
Danny has to pay $300
