A wildlife biologist observes four brown bears as they attempt to catch salmon in a river in Alaska. Assume that each bear has a .7 probability of catching a fish and that the bears fishing attempts are independent. Let the random variable X be the number of bears that catch a fish. Create the probability distribution for X (rounding each to THREE decimal places).

\n" ); document.write( "Binomial Problem with n = 4; p(catch) = 0.7; p(no catch) = 0.3
\n" ); document.write( "------------
\n" ); document.write( "P(X=0) = 0.3^4 = 0.0081
