Question 4.
If we wish to study the distribution of X, the number of albino children (or children with a
rare anomaly) in families with proneness to produce such children, a convenient sampling
method is first to discover an albino child and through it obtain the albino count Xw of
the family to which it belongs. If the probability of detecting an albino is ẞ, then the
probability that a family with k albinos gets recorded is w(k) = 1 − (1 − ẞ)k, assuming
the usual independence of Bernoulli trials. In such a case
Pxw (k) = P(X = k)
=
