To calculate the probability of each event occurring you will need to know there are 7 consonants and 3 vowels. You will use this to find the probability of each set of events occurring and multiply them together.
a. 1/10 x 1/9 = 1/90 chance
b. 3/10 x 1/9 = 1/30 chance
c. 7/10 x 2/9 = 7/45 chance
d. 3/10 x 7/9 = 7/30 chance

Step by step explaination
Quarterly compounding after 5 years nets $4,133.24 in compounded interest.
As for simple interest, I made an assumption that there was a 5% per quarter interest.
20% (5yrs * 4 qtrs.) gives total interest on $2,500 in the amount of $500.
Difference is $3,633.24
Answer:
x + z = 180
x = 180 - z
y + z +10 = 180
y = 170 - z
w + z - 13 = 180
w = 193 - z
x + y + w = 180⁰
180 - z + 170 - z + 193 - z = 180
-3z = -363
z = 121⁰
