Fill in the blanks
If e1, e2, e3, e4 are the four elementary outcomes in a sample space and P(e1) =.1, P(e2) = .5, P (e3) = .1, then the probability of e4 is ______.
Given data:
P (e1) = 0.1
P (e2) = 0.5
P (e3) = 0.1
Now, we know that,
Sum of all probabilities = 1
Thus,
P (e1) + P (e2) + P (e3) + P (e4) = 1
0.1+ 0.5 + 0.1 + P (e4) = 1
P (e4) = 1 – 0.7
Thus, P (e4) = 0.3
Answer: 0.3
