C. water left: 50,000 -  80(48)

Step-by-step explanation:

Recall that there are only 24 hours in a single day, then 2 days will have 48 hours in total: so the water loss will be [ 80(48) ] litres

Water left: total amount - water lost

water left: 50,000 -  80(48)

water left: 50,000 - 3,840

water left: 46,160

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%
