Probabilities P(R/W) and P(W/R) don't have the same value

P(R/W): the probability of plucking a red rose the second time, given that for the first time white rose has been plucked

P(W/R): the probability of plucking a white rose the second time, given that for the first time red rose has been plucked

Probability:

Probability is synonymous with possibility. It is a mathematical branch that deals with the occurrence of a random event. The value ranges from zero to one. Probability has been introduced in mathematics to predict the likelihood of events occurring. Probability is defined as the degree to which something is likely to occur.

P(R/W)= p( red and white )/ P (white) and  P(W/R)=p( red and white )/ P (red)

as P(W)≠P(R)      

P(R/W)≠P(W/R)

Therefore, Probabilities P(R/W) and P(W/R) don't have the same value
