MEM 361 Engineering Reliability
Problem Set 1
1) Let the random variable X be defined as the product of the two numbers when 2 dice
are rolled.
• List all possible values of X by this mechanism;
• Determine the theoretical probability function, f(x);
• Sketch a bar-chart for f(x);
• Compute F(25), explain the meaning of F(25);
• Compute R(15), explain the meaning of R(15);
• Show that the sum of all possible value of f(x) equals to one.
