U. s postal service regulations state that a package can be mailed using parcel post rates is it weighs no more that 70 pounds. what is the maximum number of books weighing 12 pounds each that can be mailed in one box using parcel post rates

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%

the answer is ! ?
