Question
The random-number generator on calculators randomly generates a number between 0 and 1 The random variable X, the number generated, follows a uniform probability distribution. (a) Identify the graph of the uniform density function. (b) What is the probability of generating a number between 0.52 and 0.89? (c) What is the probability of generating a number greater than 0.91? (a) Choose the correct graph of the uniform density function below. ??.

X ~ U (0 , 1)
a) Option-C) is the correct graph
b) P(0.52 < X < 0.89) = (0.89 - 0.52) / (1 - 0) = 0.37
c) P(X > 0.91) = (1 - 0.91) / (1 - 0) = 0.09
