Question

E and F are events in a sample space S for which

P(E) = 0.4, P(F) = 0.3, P(E u F) = 0.5

Find the probability P ( E I F) Round your answer to 2 decimal places. there is supposed to be a line over the F

Answer 1

can u make the question more clear

Answer 2

do u mean P(E intersection F)

Answer 3

yes i do

Answer 4

.2

Answer 5

that was incorrect

Answer 6

oh sorry i messed it up

Answer 7

i think thats how you would figure F n U

Answer 8

* F n E

Answer 9

1.66

Answer 10

how did you get 1.66?

Answer 11

oh I'm sorry it's .66. First, it's easier to draw a venn diagram of E and F. THey give you what each variable stands for and the union as well so E intersect F has to be .2 in order for E U F to be .5. Once you know the intersection plug it into the formula E n F/ F

Answer 12

the question was fin the probability of E given F right? It's the conditional probability

Answer 13

hashir did you see what i wrote on twiddla?

Answer 14

yup
