The random variable X is exponentially distributed, where X represents the waiting time to see a shooting star during a meteor shower. If X has an average value of 49 seconds, what are the parameters of the exponential distribution

But also we can define the variable in terms of like this:

And usually this notation is better since the probability density function is defined as:

Step-by-step explanation:

We know that the random variable X who represents the waiting time to see a shooting star during a meteor shower follows an exponential distribution and for this case we can write this as:

But also we can define the variable in terms of like this:

And usually this notation is better since the probability density function is defined as:
