Examlex · Accepted Answer

The Answer is a.

\begin{array} { l } P ( ext { neither ham nor turkey } ) \= 1 - P ( ext { ham } \cup ext { turkey } ) \= 1 - [ P ( ext { ham } ) + P ( ext { turkey } ) - P ( ext { ham } \cap ext { turkey } ) ] \= 1 - [ 0.44 + 0.58 - 0.16 ] = 1 - 0.86 = 0.14\end{array}

Or, using the Venn diagram at the right,

14 \%

b.

\begin{aligned}P ( ext { ham only } ) & = P ( ext { ham } ) - P ( ext { ham } \cap ext { turkey } ) \& = 0.44 - 0.16 \& = 0.28\end{aligned}

Or, using Venn Diagram at the right,

28 \%

.

c.

\quad P (

ham

\mid

turkey

) = \frac { P ( ext { ham } \cap ext { turkey } ) } { P ( ext { turkey } ) } = \frac { 0.16 } { 0.58 } = 0.2759
