a. The probability of picking exactly two $10 bills is 
b. The probability of picking at most one $5 bill is 
<em><u>Explanation</u></em>
Number of $10 bills 
and number of $5 bills 
Total number of bills= 5+3 = 8. You need to randomly pick 4 bills, so the total possible outcome
<u>a. </u>
For getting exactly two $10 bills, you need to pick two $10 bills and two $5 bills. That means we will pick two $10 bill from 5 bills and two $5 bills from 3 bills.
So, the probability 
<u>b.</u>
For getting at most one $5 bill, you need to pick <u>either zero or one</u> $5 bill.
If you pick <em>zero</em> $5 bill, that means there are <em>four</em><em> </em>$10 bills
and if you pick <em>one </em>$5 bill, that means there are <em>three </em>$10 bills.
So, the probability

Answer:
Simplifying
(20m + 3) + -1(7m + -5) = 0
Reorder the terms:
(3 + 20m) + -1(7m + -5) = 0
Remove parenthesis around (3 + 20m)
3 + 20m + -1(7m + -5) = 0
Reorder the terms:
3 + 20m + -1(-5 + 7m) = 0
3 + 20m + (-5 * -1 + 7m * -1) = 0
3 + 20m + (5 + -7m) = 0
Reorder the terms:
3 + 5 + 20m + -7m = 0
Combine like terms: 3 + 5 = 8
8 + 20m + -7m = 0
Combine like terms: 20m + -7m = 13m
8 + 13m = 0
Solving
8 + 13m = 0
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -8 + 13m = 0 + -8
Combine like terms: 8 + -8 = 0
0 + 13m = 0 + -8
13m = 0 + -8
Combine like terms: 0 + -8 = -8
13m = -8
Divide each side by '13'.
m = -0.6153846154

Answer:
∠ S = 28°
Step-by-step explanation:
Complementary angles sum to 90°, that is
∠ R + ∠ S = 90°, substitute
62° + ∠ S = 90° ( subtract 62° from both sides )
∠ S = 28°
