Determine whether the variable x has a binomial distribution in each of the following cases. if it does, explain why and determine the values of the parameters n and p. if it doesn't, explain why not.

a) you toss five fair coins -- a loonie, a quater, a dime, a nickel and a penny.
x = number of coins that land on heads

b) you select one row in the random digits table b from the textbook.
