A. the plane parallel to the x-y plane containing the point (-7, 0, 0). b. the line parallel to the y axis containing the point (-7, 0, 0). c. the line parallel to the z axis containing the point (-7, 0, 0). d. the line in which the planes x=7 and z=0 intersect.

what is the question?

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
