Question 977318
 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). 
Now, give the following probability: 
P(X=1)= 4C!*0.7*0.3^3 = binompdf(4,0.7,1) = 0.076
