Step-by-step explanation:
A goblet contains 3 red balls, 2 green balls and 6 blue balls.
Total balls = 3 + 2 + 6 = 11 balls
we choose a ball and then another ball without putting the first one back.
The probability that the first ball will be red =
= 
Second event is done without replacing the first ball so total ball will be 10
The probability that the second ball will be blue =
=
= 
P =
×
= 
The probability that the first ball will be red and the second ball will be blue is
