bobbie71G 2021-09-14a simple binary communication channel carries messages by using only two signals, say 0 and 1. We assume that, for a given binary channel, 40% of the time a | is transmitted. 0.90% of the time, a transmitted 0 will be correctly received. and the probability that a transmitted | is correctly received is 0.95. given a | is received, the probability that 1 was transmitted.
0.90% of the time, a transmitted 0 will be correctly received.

abondantQ 2021-09-14The National Vaccine Information Center estimates that 90% of Americans have
had chickenpox by the time they reach adulthood.
Suppose we take a random sample of 100 American adults. Is the use of the binomial distribution
appropriate for calculating the probability that exactly 97 out of 100 randomly sampled American
adults had chickenpox during childhood? Explain.

Braxton Pugh 2021-09-14The Metropolis police station calls Superman an average of 3 times per hour to ask for his help. The probability that the station calls Superman in a time interval is dependent only on the length of the time interval and, furthermore, is independent of whether or not the department called Superman on any previous time interval. Superman goes on a date with Lois Lane and picks her up from her place at 7:00pm.
What is the probability that the date is interrupted 5 times during the first hour and
Lois decides to go back to the office and finish writing her article?
