a. Write an inequality(<,>, s. 2) that represents t the number of hours past midnight,
when the temperature was colder than -4 degrees Celsius. Explain or show your
reasoning.

step-by-step explanation:

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%
