Elvis Henry · Answer 1

fx (x) = [ (4! / (x!) * (4-x) !]*[ (0.3) ^x]*[ (0.7) ^ (4-x) ]

Step-by-step explanation:

F (x) is been calculated by considering X (moderate) as one outcome and low and high combined as one outcome now probability function will be same as binomial distribution

F (x) = [ (4! / (x!) * (4-x) !]*[ (0.3) ^x]*[ (0.7) ^ (4-x) ]
