There are 5 blue chips, 4 red chips and 3 yellow chips in a bag. One chip is drawn from the bag. That chip is placed back into the bag, and a second chip is drawn. What is the probability that the two selected chips are of different colors? Express your answer as a common fraction.

Step-by-step explanation:

Number of Blue(B) Chips=5

Number of Red(R) Chips=4

Number of Yellow(Y) Chips=3

Total Number of Chips=5+4+3=12

Pr(B)=5/12, Pr(R)=2/12, Pr(Y)=3/12

If two chips of different colors are selected one after the other with replacement, the following combinations are possible.

BR, BY, RB, RY, YB, YR

The probability that the two selected chips are of different colors

Pr(BR OR BY OR RB OR RY OR YB OR YR)=

=

=

the correct answer is x/3+10≥32

hope this !

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
