lets put in the mind first we are finding a probability for without replacement.
Here we have 6 green,3 blue,1red balls
Probability of picking a green ball=Total Green/Total
which is going to be P1 =6/6+3+1=6/10=0.6
Now we are not putting back green ball in the bag again
Probability of Blue ball=Total blue balls/Total(new)
P2 =3/9=0.33
Now total will become 1 less than before as we did not put green ball back in the bag.
Now add them up =p1+p2=0.6+0.33=0.27

Answer: [tex]\dfrac{3}{26}[/tex]
Step-by-step explanation:
Given: The number of green balls in bag =6
Total number of balls = [tex]3+6+3+1=13[/tex]
The probability of drawing first ball is green is given by :-
[tex]P(G)=\dfrac{6}{13}[/tex]
Since he didin't replace first ball, then the total number of remains = 12
The number of blue balls in the bag = 3
The probability of drawing second ball is blue is given by :-
[tex]P(B)=\dfrac{3}{12}[/tex]
Now, the probability that the juggler first draws a green ball followed by a blue ball is given by :-
[tex]P(G)\times P(B)=\dfrac{6}{13}\times\dfrac{3}{12}=\dfrac{3}{26}[/tex]
The probability that the juggler first draws a green ball followed by a blue ball : [tex]\dfrac{3}{26}[/tex]
