The sample space for an experiment contains five sample EES points with probabilities as shown in the table. Find the probability of each of the following events:
Sample Points Probabilities
1 ............................ .05
2 ............................ .20
3 ............................ .30
4 ............................ .30
5 ............................ .15
A: {Either 1, 2, or 3 occurs}
B: {Either 1, 3, or 5 occurs}
C: {4 does not occur}
