Let c = P(event C occurs)
Let d = P(event D occurs)
The probability that independent events C and D will both occur is 0.11
Since events C and D are independent, we can conclude that \(cd = 0.11\)
So if we take this equation and divide both sides by \(d\), we get: \(c=\frac{0.11}{d}\)
So our quantities become:
Quantity A: \(\frac{0.11}{d}\)
Quantity B: 0.09
Since all probabilities can range from 0 to 1, the smallest possible value of \(\frac{0.11}{d}\) occurs when \(d = 1\), in which case \(\frac{0.11}{d}=\frac{0.11}{1}=0.11\)
This means Quantity A must be greater than or equal to 0.11

how is smallest possible value is when d=1...shouldn't that be greatest??
and shouldn't ans be "d"?
Please explain.
Let c = P(event C occurs)
Let d = P(event D occurs)
The probability that independent events C and D will both occur is 0.11
Since events C and D are independent, we can conclude that \(cd = 0.11\)
So if we take this equation and divide both sides by \(d\), we get: \(c=\frac{0.11}{d}\)
So our quantities become:
Quantity A: \(\frac{0.11}{d}\)
Quantity B: 0.09
Since all probabilities can range from 0 to 1, the smallest possible value of \(\frac{0.11}{d}\) occurs when \(d = 1\), in which case \(\frac{0.11}{d}=\frac{0.11}{1}=0.11\)
This means Quantity A must be greater than or equal to 0.11
Answer: A
