Answer:B
Step-by-step explanation:
To solve for P(QIR) we use the formula:
P(QIR)=[P(Q∩R)]/P(R)
But from the diagram:
P(Q∩R)=3/22
P(R)=7/22
hence
P(QIR)=3/22÷7/22=3/7
c. interest Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest
