The soft crash

A certain piece of software is found to fail, on average, every 2 days. Plot the graph of the probability density function of the exponential distribution with lambda=0.5, i.e.

y(t)=0.5*e^(-0.5*t).

Use values of the integral found on the graph to find the probability of failure of the software:
(a) within a single day;
(b) within 4 days.
