An exercise class had 20 people. if each person produced 2,200 btus of body heat during the class and the room is 30 ft × 40 ft × 15 ft, how many btus per cubic foot did they produce? (to the nearest hundredth) a) 0.12 btus/ft3 b) 1.83 btus/ft3 c) 2.44 btus/ft3 d) 36.66 btus/ft3

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%
