Answer:
option B
Step-by-step explanation:
Given in the question a complex fraction
<h3>Step1</h3>To divide complex numbers, you must multiply by the conjugate. To find the conjugate of a complex number all you have to do is change the sign between the two terms in the denominator.
Distribute (or FOIL) in both the numerator and denominator to remove the parenthesis.
Simplify the powers of i, specifically remember that i² = –1.
simply
P(r/w) is the probability of picking a red rose at first picking and a white rose at second picking.
P(w/r) is the probability of picking a white rose at first picking and a red rose at second picking.
P(r/w) =
×
= 
P(w/r) =
×
=
Notice that the second fraction is out of 18 because the second picking of rose will be out of 18 since the first rose is not replaced.
P(r/w) equals to P(w/r)
P(w/r) is the probability of picking a white rose at first picking and a red rose at second picking.
P(r/w) =
P(w/r) =
Notice that the second fraction is out of 18 because the second picking of rose will be out of 18 since the first rose is not replaced.
P(r/w) equals to P(w/r)
