Answer:
x = 
Step-by-step explanation:
= 5 ( multiply both sides by x to clear the fraction )
1 = 5x ( divide both sides by 5 )
= x
Answer:
a) P(1) = 0.1637
b) 
c) E(x) = 0.2
Step-by-step explanation:
If X follows a poisson distribution, the probability that a disk has exactly x missing pulses is:

Where m is the mean and it is equal to the value of lambda. So, replacing the value of m by 0.2, we get that the probability that a disk has exactly one missing pulse is equal to:

Additionally, the probability that a disk has at least two missing pulses can be calculated as:

Where
.
Then,
and
are calculated as:

Finally, In the poisson distribution, E(x) is equal to lambda. So E(x) = 0.2

Answer: The width of the field = 120
Step-by-step explanation: This question can be solved by first opening of the bracket, then relating the equation to quadratic general equation and finally solve for domain of X by using quadratic formula.
