An urn contains 3 red, 8 yellow and 13 green balls; another urn contains 5 red, 7 yellow and 6 green balls. we pick one ball from each urn at random. find the probability that both balls are of the same color.

The number of possible outcomes is 24×18.

The number of favorable outcomes are as follows: (3×5)+(8×7)+(13×6)

The probability is simply:

(3×5)+(8×7)+(13×6)/24×18=149/432

Step-by-step explanation:

if you was gonna solve for a, a is a   < -12

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
