For each following experiment, determine if it is binomial. If this is the case, determine the value of parameters n and p. a) We choose 10 children at random and record their weight at birth. b) Among the 10 children born in a hospital, we want to know how many weigh less than 2.5 kg, which happens with a probability of 6.2% according to Statistics Canada. c) We simultaneously draw 5 cards from a deck of 52 cards and count the number of heart cards obtained. d) We draw successively with replacement 5 cards from a deck of 52 cards and we count the number of heart cards obtained. e) We draw successively and with replacement cards from a deck of 52 cards until we obtain a heart. We counts the number of prints required. Note: It is crucial that the n Bernoulli tests are identical (constant p) and independent.

b) Among the 10 children born in a hospital, we want to know how many weigh less than 2.5 kg, which happens with
a probability of 6.2% according to Statistics Canada.
c) We simultaneously draw 5 cards from a deck of 52 cards and count the number of heart cards obtained.
d) We draw successively with replacement 5 cards from a deck of 52 cards and we count the number of heart cards
obtained.
e) We draw successively and with replacement cards from a deck of 52 cards until we obtain a heart. We
counts the number of prints required.
