1 Let P(x) = µx . e-µx! and let µ=10. Find P(9)

Solution:

P(x) = µx . e-µx! Given.

P(x) = 10x . e-10x!Substitute the value of µ=10 from the given.

Finding P(9):

P(x) = 10x . e-10x!From P(x) using the value of µ=10.

P(9) = 109 . e-109!Substitute P(x) to P(9).

P(9) = 1099! . e10Rewrite the expression with positive integer exponent.

P(9) = 1, 000, 000, 000362, 880 . e10Simplify.

P(9) = 1,562,500567 e10 Final answer
