Show that if z is a nonzero complex number, then there exist exactly n complex numbers w such that wn = z. If z is in polar form, write w in polar form. Represent the vectors w in the complex plane.

Probability 3.13.7 ● Randomness We call a phenomenon random if individual outcomes are uncertain. Chance behaviors unpredictable in the short run but has a regular and predictable pattern in the long run. ● Probability ○ The probability of any outcome of a random phenomenon is the proportion of times the outcome would occur in a very long series of repetitions. ○ If, under a given assumption, the probability of a particular observed event is extremely small, we conclude that the assumption is probably not correct. ■ Classical method is use when all the experimental
