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%
-12 > a
-11 > 1 + a
subtract 1 from each side
-11 -1> 1 -1+ a
