Answer:
He received 92 points total and he only lost 8 points overall.
Step-by-step explanation:
Ned has 100 points to start because each question counts as 4 points and there is 25 question. He lost 16 points overall because he missed 4 question and each count as 4. Then he lost 16 points and is left with 84 points. Finally he earns 8 more points and is left of with 92 points.
Total points: 25 x 4 = 100
Total points lost: 4 x 4 = 16
Point before extra credit: 100 - 16 = 84
Points after extra credit: 84 + 8 = 92
Number Sentence: 100 - (4 x 4) = a + 8 = 92

Flipping two coins gives four possibilities: HH, HT, TH, TT
So P(TT)=1/4
So we'd expect a quarter of the trials to be two tails.
