A bag contains 3 red marbles and 3 blue marbles. What is the probability that the first marble drawn is red and the 2nd marble drawn is blue?

there are a total of 7 marbles

Step-by-step explanation:

The chance of the first marble being blue is 4/7. Now we only have 6 marbles in the bag (3 red and 3 blue)

The chance of the second marble being blue is 3/6

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

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 %
