Probability Distribution I A random variablex has this probability distribution:x 0 1 2 34 5p(x) .1 .3 .4 .1 ? .05a. Find p(4).b. Construct a probability histogram to describe p(x).c. Find m, s2, and s.d. Locate the interval m 2s on the x-axis of the histogram.What is the probability that x will fall intothis interval?e. If you were to select a very large number of valuesof x from the population, would most fall into theinterval m 2s? Explain.
