Consider randomly selecting a computer$-$science major student, and let $A,B,$ and $C$ be the event that the selected student knows Python, Jave, and Fortran, respectively. In addition to $P(A)=0\mathrm{.}6,P(B)=0\mathrm{.}4,$ and $P(C)=0\mathrm{.}2,$ suppose that $P(AB)=0\mathrm{.}3,P(AC)=0\mathrm{.}15,P(BC)=0\mathrm{.}1,$ and $P(ABC)=0\mathrm{.}08.$
