Given expression: 1/4 (16-12x).
Solution: We can see that 1/4 is in front of paranthesis.
That represents multiplication of 1/4 with (16-12x)
In order to 1/4 with (16-12x), we need to distribute 1/4 over (16-12x).
On distributing 1/4 over (16-12x), we get
1/4 (16-2x) = 1/4 * 16 + 1/4 * (-12x).
On multiplying 1/4*16, we get 16/4 and 1/4 * (-12x) = -12x/4.
16/4 could be simplify to 4 and -12x/4 could be simplify to -3x.
So, final answer would be 4 - 3x.
Therefore, second option is our correct option, that is 4 - 3x.

Answer:
Probability that student has a good grade = 0.525
Step-by-step explanation:
Given
Chances of earning a good grade when assignments are done on time = 0.80
Chances of earning a good grade when assignments are finished during class or late = 0.30
Chances of earning a good grade when assignments are not done at all = 0.05
% of students who completed assignment on time = 0.50
% of students who completed assignment during class = 0.40
% of students who did not completed assignment at all = 0.10
Probability that student has a good grade
= (0.80 *0.50) + (0.30*0.40) + (0.05*0.10)
= 0.525
