Answer:
0.11
Step-by-step explanation:
Probability that house sale will increase = P(A) = 0.25
Probability that interest rate on house loans will go up = P(B) = 0.74
Probability that either house sales will go up or interest rates will go up = P(A or B ) = 0.89
We have to find the probability that neither house sales nor interest rates will increase. This event is the compliment of the event that either house sales will go up or interest rates will go up.
i.e.
Probability that neither house sales nor interest rates will increase = 

Using the value of P(A U B), we get:

The probability that neither house sales nor interest rates will increase during the next 6 months is 0.11
0.5s + 1 = 7 + 4.5s Subtract 4.5s from both sides
-4s + 1 = 7 Subtract 1 from both sides
-4s = 6 Divide both sides by -4
s = -

Simplify
s = -
Answer: Php. 3,300
Step-by-step explanation:
Assuming this is simple interest, the amount he would earn from Stacy after 2 years is:
= Amount loaned out * Interest rate * Number of years
= 7,500 * 10% * 2
= Php 1,500
Amount from Torrie:
= 7,500 * 12% * 2
= Php. 1,800
The total interest received is:
= 1,500 + 1,800
= Php. 3,300
