I was wondering if you could help me with two word problems that have to do with probability, average, standard deviation, and variance. The first is : If the probability of a flight to have difficulties with landing is of 1%, Determine the average, variance, and standard deviation of 300 flights. The second is: The 16% of bolts produced by a machine are defective. Determine the average, variance, and standard deviation in a total of 200 bolts.
