Kailynn has a bag with an equal number of red, yellow, and blue marbles. She makes a tree diagram to show the sample space if she randomly selects two
marbles out of the bag.

What is the probability that both marbles selected are different colors?

6/9

Step-by-step explanation:

Probability is the likelihood or occurrence of an event. Probability is the ratio of the total number of possible outcomes to the total outcomes. That is:

Probability = total possible outcomes / total outcomes

From the tree diagram we can see that:

total outcomes = {RR, RY, RB, YR, YY, YB, BR, BY, BB} = 9

getting different colors = {RY, RB, YR, YB, BR, BY} = 6

Therefore, the probability that both marbles selected are different colors = number of different colors / total outcomes

The probability that both marbles selected are different colors = 6 / 9

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
