An urn contains g green marbles and b blue marbles. If 1 green marbles and 5 blue marbles are added, and then one marble is selected at random from the urn, what is the probability that a blue marble will be drawn?	Choose the correct choice from the following answers.
A) b/(b+g) B) (b+5)/(g+3) C) (b+5)/(b+g+8) D) (b+5)/(b+g+6) E) b/(b+g+5)
no of fav outcomes i.e. blue MArbles = b+5   Total no of outcomes i.e. total Marbles = (b+5)+(g+1)= b+g+6   probability = (b+5) /(b+g+6)   Answer (b+5)/(b+g+6)
