This example is frivolous but shows how the normal distribution can approximate even sums of discrete r.v.'s. In an orchard, suppose the number X of worms in an apple has probability function: 0.03 0.025 0.02 0.015 0.01 0.005 920 224.5 230 x 236 240 245 250 266 260.5 13 0 1 2 3 f(x) 4 .3 .2 .1 Find the probability a basket with 250 apples in it has between 225 and 260 (inclusive) worms in it.
