21% of a certain breed of rabbits are born with long hair. What is the probability that in a litter of 12 rabbits, exactly 2 will have long hair? (Give your answer correct to three decimal places.)
1=.21=.79
0.79^12=0.05909
2-0.0591=1.94

  • math check -

    Prob(long hair) = .21
    prob(not long hair) = .79

    prob(exactly 2 of 12 to have long hair)
    = C(12,2) (.21^2)(.79^10) = appr .2756
