How do you find the probability of drawing marbles?
The probability of drawing a red marble = 2/5. The probability of drawing a blue marble = 1/5. The 1/5 probability of drawing a blue marble assumes all 5 marbles are in the jar.
How many marbles are in a box of marbles?
Ex 15.1, 9 A box contains 5 red marbles, 8 white marbles and 4 green marbles. One marble is taken out of the box at random. What is the probability that the marble taken out will be (i) red?
What is the probability that 2 randomly chosen marbles are not pink?
To obtain the probability that is asked, simply compute 1 – (2/9) = 7/9. The probability that the 2 randomly chosen marbles are not both pink is 7/9.
What is the value of P (marble taken out is not green)?
P (marble taken out is not green) = P (marble taken out is white) + P (marble taken out is red) = 8/17 + 5/17 = 13/17 Ex 15.1, 9 (Method 2) A box contains 5 red marbles, 8 white marbles and 4 green marbles. One marble is taken out of the box at random.
