Betty had 40$ in her pocket. she bought 12 identical bags of popcorn. betty was left with 10$ after buying the popcorn. what was the price, in dollars, of each bag of popcorn? a) 0.55 b) 2.50 c) 4.17 d) 5.20

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%

a is the right answer
