b. If the frequency of the second-largest wavelength is 50.0 Hz, what is the frequency of the third-longest wave length?
Study the binomial distribution table. Notice that the probability of success on a single trial p ranges from 0.01 to 0.95. Some binomial distribution tables stop at 0.50 because of the symmetry in the table. Let's look for that symmetry. Consider the section of the table for which
(a) Compare P(3 successes), where
(b) Compare P(3 or more successes), where
P(3 or more successes), where
(c) Find the value of P(4 successes), where
For what value of r is P(r successes) the same using
