Well if there were 50 questions it would be 2 points each so if he ended up with 96% he must have missed 2 questions
1. 4
2. 9
3. 21

b= $39.98
I hope this helps
Step-by-step explanation:
Adam is correct because when the hundreds and tens digit changes in 708, that means that the 7 and 0 will change into 6 and 9
Let's think of an example which would better help visualize this situation.
1) Someone exercises a lot so they can concentrate more on their homework (here running and concentration on homework are dependent events)
2) Someone exercises a lot because they wear a blue t-shirt (here, you can clearly see that wearing a blue shirt and exercising are not related. These events are independent).
Now concentrating on P(a | b) = Probability a occurred if b occurred.
It does not matter if b occurred (just like it didn't matter that the person wore a blue shirt which meant that they exercised) for the outcome a to occur.
Therefore, probability of P(a | b) = P(a)
P(a | b) = 0.65
Hope I helped :)
