Question

A bag contains 16 colored balls. Six are green, 7 are red and 3 are white. A ball is chosen, without looking into the bag. Find the probability that the ball chosen is: 

white or green 

 

Answer 1

Balls in the  bag =16= Number of balls that could be drawn 

n(s)=16 

E= Event of drawing a green or a white ball=number of green balls+number of white balls=6+3=9 

n(E)=9 

Probability of drawing a green or a white ball=`(n(E))/(n(s))=9/16`
