Question

If X is a continuous uniform random variable taking values between 0 and 1, then the value of
the probability P(X = 0.2) is? how do i calculate using ti-84?

Answer 1

If the variable is continuous rather than discrete, the probability of any specific exact X value is infinitessimal.

 

Usually the probabilities are required for an 'area under the curve' corresponding to a < X < b (and it doesn't matter if the < symbols are ≤ symbols.
