The Probabilty That Both Marbles Are The Same Color

And so this is sometimes the event in question right over here is picking the yellow marble.

The probabilty that both marbles are the same color. A the probability that the first marble is red and the second is white. The answer is the option a. Find the probability of pulling a yellow marble from a bag with 3 yellow 2 red 2 green and 1 blue i m assuming marbles. Probability of taking out a black marble.

One bag contains three white marbles and five black marbles and a second bag contains four white marbles and six black marbles. So they say the probability i ll just say p for probability. Note that the events are independent. For green we have the same answer as above which is 1 15.

The marble that you take out in the second bag does not depend on the one you took out in the first bag. The probability of picking a yellow marble. P 9 23 8 22 b the probability that both are the same color. A person draws one marble from each bag.

The event that the marbles are different colors is the complement of the event that the marbles are the same color. Draw two w o replacement. Thus calculate the probability that the marbles are the same color then subtract this probability from 1 to find the probability they are different colors. B either we have 2 green or 2 white.

For white we have a 4 6 prob. Then the probability that both marbles are of the same color is. White white or black black. P 2 green 3 13 2 12 1 26 p 2 yellow 6 13 5 12 5 26.

9 red marbles 8 white marbles and 6 blue marbles. P 2r 2w 2b. This give the prob.
