Determine if each situation is dependent or independent.
A bag contains ten red, seven white, and three blue marbles.
If three marbles area selected in succession, without replacement, what is the probability
that a blue marble, then white, then red is selected?

Determine if each situation is dependent or independent.
A bag contains ten red, seven white, and three blue marbles.
If three marbles area selected in succession, without replacement, what is the probability 
that a blue marble, then white, then red is selected?

first select the blue i.e.,   them probabulity is 3c1/20c1
then white i.e.,  the prob is 7c1/19c1
then red   10c1/18c1

  the multyply 3 of them...........
(3c1*7c1*10c1)/(20c1*19c1*18c1)

anonymous · Answer

then the total probabulity is... (3*7*10)/(20*19*18)....

id you get it.......@KeyriMelissa 
or i should explain more....

@chetan552 its asking me if its Determine if each situation is dependent or independent.

anonymous · Answer

The question clearly says thet it is dependent....

anonymous · Answer

there is mentioned that without replacement...
if they give with replcement then we can say that it is independent...
hear it is dependent...
