It is known that 90% of mice inoculated with a serum are protected from a certain disease (i.e. do not contract the disease). If 100 mice are inoculated use Chebyshev’s theorem to estimate the probability that: (a) Between 4 and 16 mice contract the disease (b) Less than 69 mice do not contract the disease.
