A bag contains 7 red, 4 blue, and 6 white marbles.
Find the probability of randomly picking a red marble, replacing it, and then picking a blue marble.

28/289

Step-by-step explanation:

7 red, 4 blue, and 6 white  = 17 marbles

P ( red ) = number of red / total

             = 7/17

Replace the marble

7 red, 4 blue, and 6 white  = 17 marbles

P ( blue ) = number of blue / total

             = 4/17

P (red, replace, blue) = 7/17* 4/17

                                    =28/289

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 %  

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
