11. y=-1/3x-4
Plug the slope into m in y=mx+b and then plug in your point and solve for b. You get C
12. Parallel means it has the same slope or the same m, so the -1/2 stays the same and you plug that and your point into the y=mx+b and solve for b again. You get D, y=-1/2x-9
13. Perpendicular means that the slope is the opposite reciprocal so you flip it and multiply it by -1. You then plug that in for your slope and plug in your points and you get A, y=9x+13
Approximately 68% of a normal distribution lies within one standard deviation of the mean, so this corresponds to students with scores between

Probability = # of positive events / # of all possible events
As the event B restricts the number of consecutive cards that result in a positive outcome (only consecutive face cards), it means that the numerador of the formula to find the probability is smaller, while the denominator remains unchanged.
That means that the probabilty calculated for the event A is greater than the probability of the event B.
So, the answer is that the event A is more likely than event B.
