In an experiment, the probability of the event E is known to be .4. Also the probability of the event F is .8,and the probability of E∪F is 1.

i) Compute the probability of these events: P(E∩F)=

P(E-F)=

ii) Suppose the experiment is run twice in succession. What is the probability of the event E occuring at least once? Answer:?
