    This is a uniform distribution. You need to shade the area corresponding to -1 \leq t \leq 1 (why) and then say what proportion of the total area it is, either noting that the total area under the line is equal 1 (why?) or using symmetry.

    If you need more help, you will need to say exactly where you're still stuck.

    Ok thank you, but I am still confused as to which part of the graph that I shade. Could you be more specific as to which part of the graph I am shading, such as the left or right side?

    Well, I'd assume that t = 0 corresponds to the class finishing exactly on time. So, with this in mind, go back and think about the values of t I gave in my first reply.
