Answer:
B) -2 3/4>-1 1/4
Step-by-step explanation:
The more negative something is(bigger the value) the less it's going to be because it is that much far away from zero. You can see that -2 3/4 is farther away from zero in the negative side than -1 1/4.

Answer:
D) 0.211
Step-by-step explanation:
The probability of getting a correct answer is 1/4, so the probability of an incorrect answer is 3/4.
The probability of 2 correct and 2 incorrect is (1/4)(1/4)(3/4)(3/4) = 9/256.
There are C(4,2) = 4·3/(2·1) = 6 ways to have some combination of 2 correct and 2 incorrect out of 4 questions. So, the probability of that result is ...
... 6 · 9/256 = 27/128 =0.2109375 ≈ 0.211
