Part 1.

When a probability experiment only has two possible outcomes and you know the probability of one outcome, you can find the probability of the other outcome by computing (the complementary probability, using the addition rule, using the multiplication rule)

To find the probability of two (mutually exclusive, independent) events both occurring, you may simply multiply their individual probabilities.

When two scenarios are (mutually exclusive, independent) , we can simply add their probabilities together to find the probability that one scenario or the other scenario occurs.

Part 2.

When using the choose function, the top number n represents (number of successes, number of trials, probability) and the bottom number k represents (number of trials, probability, number of successes )

Part 3.

Suppose you flip a coin 6 times. For each of the 6 trials there are 2 possible outcomes, heads or tails. Heads and tails each have a probability of 0.5 per trial. Consider "heads" to be a success. What is the probability that you only have 2 successes in 6 trials? Round your answer to four digits after the decimal point.

3) Suppose you wanted to simulate possible profit outcomes, and you know that revenues have a 30% likelihood of being $2 million, 12% likelihood of being $3.5 million, 48% likelihood of being $4 million, and 10% likelihood of being $4.5 million. Furthermore, Costs have a 30% probability of being $3.25 million and a 70% probability of being $3.5 million. Using Excel, simulate 100 instances of profit. Calculate average, minimum, and maximum profits. Is 100 instances sufficient? Why or why not?
