Answer:
Step-by-step explanation:
Problem One
Blue =   5
Black  =2
Red    = 3
First of all there are 10 marbles, 2 of which are black.
That means that 8 others are not black
You can draw any one of the 8.
P(not black) = 8/10 = 4/5
Problem Two
There are 10 marbles in all
3 of them are red.
P(Red) = 3/10  
 
        
             
        
        
        
Answer:
D m =  
Step-by-step explanation:
factor the expressions in the denominator and the numerator to simplify the expression:
=> 
=> 
to make a fraction undefined, the numerator should be 0, thus, we substitute the values of m from the options into the denominator to make the denominator equals to 0:
=>  =
 =  =
 = 
in this case, the values of m from option D make the denominator of the fraction equals 0.
