Given information
Use the following information to answer the next 
exercises. Carbo
is a radioactive element with a half-life of about 
years. Carbon-
is said to decay exponentially. The decay rate is 
We start with one gram of carbon
. We are interested in the time (years) it takes to decay carbon-.
Step-by-step explanation
Step 1.
According to the given information, the random variable 
denotes the time in years carbon- decays. This follows the exponential distribution.
Hence, the distribution of is exponential.
