Mrs. sullivan had 18 erasers at the end of the day. she remembered giving out 14 and getting back 11, then giving out 13 and getting back 14. how many erasers did she start with?

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%
