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
Answer:
First number --> x
Second number --> y
x + y = 14 --> x = 14 - y
x - y = 4
so
14 - y - y = 4
14 - 2y = 4
2y = 10
y = 5
so
x = 14 -5
x = 9
Im not sure if this is right but all you have to do is divide $150,000 among Juan, Felix and Sasha
