Abag contains 4 red marbles and 5 blue marbles. what is the probability of randomly selecting a blue marble and then, without replacing it, selecting a red marblea bag contains 4 red marbles and 5 blue marbles. what is the probability of randomly selecting a blue marble and then, without replacing it, selecting a red marble

Step-by-step explanation:

P(blue) = 5 blue out of 9 total =

P(red) = 4 red out of 8 remaining = =  simplified

P(blue)    and     P(red)

           x        

=                    

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
