Suppose a uniform random variable can be used to describe the outcome of an experiment with the outcomes ranging from
20 to 70. What is the probability that this experiment results in an outcome less than 30?
Homework Answers
Solution :
Given that,
a = 20
b = 70
P(x < c) = (c - a) / (b - a)
P(x < 30) = (30 - 20) / (70 - 20) = 0.2
Probability = 0.2

What does it mean to say that the trials of an experiment are independent? The outcome of one trial does not affect the probability of success on any other trial. One outcome is more likely to happen than the other outcomes. The outcome of one trial affects the probability of success on any other trial. One outcome is less likely to happen than the other outcomes.
