Suppose a uniform random variable can be used to describe the outcome of an experiment with outcomes ranging from 20 to 90. What is the probability that this experiment results in an outcome less than 30? Round to the nearest hundredth when necessary.
A) 0.14
B) 1
C) 0.09
D) 0.23

The range of the uniform distribution is from 20 to 90. The probability of an outcome less than 30 is the length of the interval from 20 to 30 divided by the total length of the interval from 20 to 90, which is (30-20)/(90-20) = 10/70 = 0.14.
