Basic Math

Part 1.

When a probability experiment only has two possible outcomes andyou know the probability of one outcome, you can find theprobability of the other outcome by computing (the complementaryprobability, using the addition rule, using the multiplicationrule)

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

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

Part 2.

When using the choose function, the top number nrepresents (number of successes, number of trials, probability) andthe 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 thereare 2 possible outcomes, heads or tails. Heads and tails each havea 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.
