Two planes intersect in a line that contain all common points of these two planes.
1. Plane named ABFE contains points A, B, F and E.
2. Plane named BFCD contains points B, F, C and D.
As you can see points B and F are common points for these two planes, then the line of intersection is BF and its notation is
Note that notation stays for segments and notation
stays for rays.
Answer: correct choice is A.

The exponential distribution is "the probability distribution of the time between events in a Poisson process (a process in which events occur continuously and independently at a constant average rate). It is a particular case of the gamma distribution". The probability density function is given by:
Solution to the problem
For this case the time between breakdowns representing our random variable T is exponentially distirbuted
So on this case we can find the value of like this:
So then our density function would be given by:
The exponential distribution is useful when we want to describe the waiting time between Poisson occurrences. If we assume that the random variable T represent the waiting time between two consecutive event, we can define the probability that 0 events occurs between the start and a time t, like this:
And on this case we are looking for this probability:
