Get started for freeCarbon-14 is a radioactive element with a half-life of about
5,730 years. Carbon-14 is said to decay exponentially. The decay rate is 0.000121. We start with one gram of carbon-14.
We are interested in the time (years) it takes to decay carbon-14. In words, define the random variable X.
A continuous probability function is restricted to the portion between x = 0 and 7. What is P(x = 10)?
Use the following information to answer the next eight exercises. A distribution is given as.
Find the percentile
According to the American Red Cross, about one out of nine people in the U.S. have Type B blood. Suppose the blood types of people arriving at a blood drive are independent. In this case, the number of Type B blood types that arrive roughly follows the Poisson distribution.
a. If people arrive, how many on average would be expected to have Type B blood?
b. What is the probability that over people out of these 100 have type B blood?
c. What is the probability that more than people arrive before a person with type B blood is found?
for a continuous probability function is , and the function is restricted to . What is ?
