Can anyone assist me with the following Stats problem?

If P(E) = 0.5, P(E of F) = 0.70 and P (E and F) = 0.05, find P(F)

I am pretty sure that should be P(E OR F), not P(E OF F)

Note that \(\displaystyle P(E \;\ or \;\ F)=P(E)+P(F)-P(E \;\ and \;\ F)\)

Plug in your givens and solve for P(F). Simple arithmetic.

Drawing a Venn diagram is a good way of doing that one
