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 0.47 and 0.8? (c) What is the probability of generating a number greater than 0.91? (a) Choose the correct graph of the uniform density function below. O A. Density 1.2 1 0.8 0.6- 0.4- 0.2 0- 0 0.2 0.4 0.6 0.8 1 1.2 O B.
