Ok, so finals are here and I need some statistics help, and any is greatly appreciated (could you please explain how you did it). Here goes,

1) The mean house price is $155,000 and standard deviation is $15,000.
a) If this was not normally distributed, what percent of the data would fall within 2.5 standard deviations?

2) 16 of every 100 TV's delivered to a factory are defective.
a) What is the probability that the first defective unit is the 10th delivered?
b) What is the probability that the defective unit is the 1st, 2nd, or 3rd delivered?
