Step-by-step explanation:
Given that an experiment results in one of the sample points E1, E2, E3, E4,
or E5.
Then P(e1) + P(e2) + P(e3) + P(e4) + P(e5) = 1
If P(E1)=0.1, P(E2)=0.1, P(e4)=0.2, and
P(E5)=0.3., then P(E1) = 1 - 0.1 - 0.1 - 0.2 - 0.3 = 0.3
Therefore, P(e3) = 0.3
Answer:
0.98
Step-by-step explanation:
Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.13 + 0.85 - 0
P(A or B) = 0.98
Note that P(A and B) is 0. This is because we are told A and B are mutually exclusive events. This means both events cannot happen simultaneously. An example would be flipping a coin to have it land on heads and tails at the same time.
