There are 10 women and 3 men in room a. one person is picked at random from room a and moved to room b, where there are already 3 women and 5 men. if a single person is then to be picked from room b, what is the probability that a woman will be picked

The probability that a woman will be picked from room B is 0.34.

Step-by-step explanation:

There are 13 persons in room A, which 10 are women. So, the probability that a woman gets picked to be transfer to room A is 10/13 = 0.77.

Then, in room B there will be a total of 9 persons, assuming that a woman got picked from room A, the probability of that a woman will be picked from room B is 9/4 = 0.44 x 0.77 = 0.34.

which expression represents the approximate length of bc?

step-by-step explanation:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
