6.50Binomial needs fixed nFor the binomial distribution,the number of trials n is a fixed number. Let X denote thenumber of girls in a randomly selected family in Canadathat has three children. Let Y denote the number of girls ina randomly selected family in Canada (that is, the numberof children could be any number). A binomial distributionapproximates well the probability distribution for one of Xand Y, but not for the other.tala. Explain why.b. Identify the case for which the binomial applies andidentify n and p.

4.56 Nonstandard dice. Nonstandard dice can produce interesting distributions of outcomes. You have two balanced, six-sided dice. One is a standard die, with faces having one, two, three, four, five, and six spots. The other die has three faces with one spot and three faces with six spots. Find the probability distribution for the total number of spots Y on the up-faces when you roll these two dice.
