Question

If E and F are events with P(E) = 0.4 and P(F) = 0.3 and P(E n F) = 0.2, find the probability of E given F. Also find P(F I E)

Answer 1

\[P(E|F)=\frac{P(E\cap F)}{P(F)}\]

Answer 2

\[P(F|E)=\frac{P(F\cap E)}{P(E)}\]

Answer 3

just plug into that second formula zarkon has :)
you can do it

Answer 4

so P(F I E) = .5

Answer 5

yes

Answer 6

and how would i find P( E I F)

Answer 7

use the very first formula he has for you

Answer 8

so .67

Answer 9

?

Answer 10

\[\frac{2}{3}\]

Answer 11

\[.\bar{6}\]

Answer 12

yep thats what i got!!!! thank you!!!!!!!!!!!

Answer 13

.6ˉ
