You can put this solution on YOUR website! When treated with antibiotics. 98% of dolphins are cured of an ear infection. if 5 dolphins are treated, find the probability that exactly 3 are cured
-------
Binomial Problem with n = 5 ; p(cure) = 0.98 ; p(not) = 0.02
-------------------
P(x = 3) = 5C3*0.98^3*0.02^2 = binompdf(5,0.98,3) = 0.0038
