15. A sample space S consists of 5 events with these probabilities: P(E1) = P(E2)=.2 P(E3)= .3 P(E4) = P(Es) a. Find the probabilities for the simple events E4 and Es. P(E4) b. Find the probabilities for these 2 events: i. M= {E1, E3, Es} ii. L= {E2, Es} P(M)= P(L) = c. List the events that are either in event M or event L or both. M or L or both = { P(M or L) = d. List the simple events that are in both event M and event L. M and L={ P(M and L) = P(Es)
