The Probabilty That Both Marbles Are The Same Color

For white we have a 4 6 prob.

The probabilty that both marbles are the same color.

For green we have the same answer as above which is 1 15. P 9 23 8 22 b the probability that both are the same color. And so this is sometimes the event in question right over here is picking the yellow marble. 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.

Draw two w o replacement. The probability of picking a yellow marble. Note that the events are independent. Find the probability that both marbles are of the same color.

The answer is the option a. 9 red marbles 8 white marbles and 6 blue marbles. One bag contains three white marbles and five black marbles and a second bag contains four white marbles and six black marbles. The event that the marbles are different colors is the complement of the event that the marbles are the same color.

White white or black black. Then the probability that both marbles are of the same color is. B either we have 2 green or 2 white. P 2r 2w 2b.

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. This give the prob. So they say the probability i ll just say p for probability. On the first pick and 3 5 on the second.

You can draw two white marbles or two black marbles. The marble that you take out in the second bag does not depend on the one you took out in the first bag. P 2 green 3 13 2 12 1 26 p 2 yellow 6 13 5 12 5 26.
