Answer:
240
Step-by-step explanation:
The x^k term will be ...
(6Ck)(x^k)(4^(6-k))
For k=4, this is ...
(6C4)(x^4)(4^2) = 15·16·x^4 = 240x^4
The coefficient of x^4 is 240.
_____
nCk = n!/(k!(n-k)!)

Answer:
Step-by-step explanation:
If a machine is replaced at some time t, then the expected time until next failure is
and the time between the checks is exponentially distributed with rate \lambda, the expected time until next failure is
Because of memory less property of the exponential The answer is
