i really dont know how to ue the Latex. it doesnt work although i try it for many times.(adsbygoogle = window.adsbygoogle || []).push({});

so, im new to this chapter. maybe this question is easy to be solved, but i cant get it.

a continuous random variable X has cumulative distribution as attached.

the question is what is the value of alpha.

i try doing like this but it doesnt give any answer though.

F(-1) = 0 = (alpha)(-1)+(alpha)
