A building contractor is preparing a bid on a new construction project. Two other contractors will be submitting bids for the same project. Based on past bidding practices, bids from the other contractors can be described by the following probability distributions:  I was able to create the simulation but my probabilities keep coming up incorrect (0.04, 0.01, 0.01). Please provide an explanation on how you found your answer

If there is a 10% chance it will rain each day for the next week, what is the probability that it will rain at least once?

A mechanical press is used to mold shapes for plastic toys. When the machine is adjusted and working well, it still produces about 6% defective toys.  The toys are manufactured in lots of 100.  What is the probability that the percent of defective toys is 11% or more?

There are seven geologic faults (and possiblymore) capable of generating a magnitude 6.7 earthquake in theregion around San Francisco. Their probabilities of rupturingby the year 2032 are 27%, 21%, 11%, 10%, 4%, 3%, and 3%.Source: Science News.a. Calculate the probability that at least one of these faults erupts by the year 2032, assuming that these are indepen-dent events. b. Scientists forecast a 62% chance of an earthquake withmagnitude at least 6.7 in the region around San Franciscoby the year 2032. Compare this with your answer from parta. Consider the realism of the assumption of independence. Also consider the role of roundoff. For example, the prob-ability of 10% for one of the faults is presumably rounded to the nearest percent, with the actual probability between9.5% and 10.5%.
