1 Properties of the Distribution are: Set number of trials - 10 in the seasonFixed ProbabilitySuccess or Failure (Win or __not Win__)All independent of each otherTherefore, only distribution that fits is binomial.2 X~B(n,p) where n [index]= number of trials = 10, p[parameter] = probability of success = 30%=0.3Therefore X~B(20,0.3)3 P(X=a) = (n!)/(a!x((n-a)!))p^{a}(1-p)^{(n-a)}Therefore, P(X=5)=[(10!)/((5!)x(5!))] x 0.3^{5}x (1 - 0.3)^{(10-5)} = 252 x 0.00243 x 0.16807 = 0.103 (3sf)
