Answer:
B. 20
Step-by-step explanation:
<em>First, you divide by 5 from both sides of equation.</em>
<em></em>
<em>Simplify, to find the answer.</em>
<em></em>
<em>, which is our answer.</em>
21-3= 18 and 18 divided by 6 equals 3 so v=3
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)
