Question 364442: A box contains four red marbles, seven white marbles and five blue marbles. If one marble is drawn at random, find the probability for each of the following: A blue marble drawn. A red or a blue marble is drawn. Neither a red nor a blue marble is drawn. Answer by amoresroy(361) (Show Source):
You can put this solution on YOUR website! A box contains four red marbles, seven white marbles and five blue marbles. If one marble is drawn at random, find the probability for each of the following: A blue marble drawn. A red or a blue marble is drawn. Neither a red nor a blue marble is drawn.
The probality a blue marble drawn
= 5/(4+7+5) = 5/16
The probability a red or a blue marble is drawn
= (4+5)/(4+7+5) = 9/16
The probability neither a red nor a blue marble is drawn
= 7 / 16
