Suppose a couple has four children. Assume that each child is equally likely to be a boy or a girl, regardless of the outcome of previous births. The following table shows the results of a simulation to determine the gender breakdown in 20 families. Number of girls 1 2 4. Probability = 0.1 - 0.2 20 읊-0.3 %3D 20 * - 0.1 20 a. Based on the simulation results, which is more likely, a 2:2 split of boys and girls or a 3:1 split in either direction? A split is more likely with a probability of b. Write out the sample space and calculate the exact probabilities for the various possible gender breakdowns. Enter the exact answer as a decimal. Number of giris 2 3 4 Probability c. Reanswer part a. using exact probabilities.
