Shannon rolls a number cube and then chooses a card from set of cards numbered 1 through 5. what is the proability that she will roll an even number and choose an odd- numbered card?

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
