Question 1153484
<br>
For a continuous random variable, the probability that the value is exactly any one number is zero.<br>
c. P(X = 66) = 0<br>
a. Given that P(X > 66) = 0.25, and now knowing that P(X = 66) is 0, P(X < 66) = 1-0.25 = 0.75.<br>
b. Given that P(20 <= X <= 66) = 0.31, and now knowing that P(X < 66) = 0.75, P(X < 20) = 0.75-0.31 = 0.44.<br>
