Estimate the difference. use benchmarks with decimal parts of 0, 0.25, 0.50, or 0.75.
5.99–2.3
a. 3.25
b. 3.50
c. 3.75

C

Step-by-step explanation:

1. 5.99 = 6

2. 2.3 = 2.25

3. 6 - 2.25 = 3.75

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%
