The wrestler gained 5.20 kilograms per month.
Step-by-step explanation:
Let,
x be the weight gained every month.
y be the original weight before weight gain.
According to given statement;
0.5x+y=80.6 Eqn 1
2x+y=88.4 Eqn 2
3.5x+y=96.2 Eqn 3
Subtracting Eqn 1 from Eqn 2
Dividing both sides by 1.5
The wrestler gained 5.20 kilograms per month.

Answer:
(a) The probability of more than one death in a corps in a year is 0.1252.
(b) The probability of no deaths in a corps over 7 years is 0.0130.
Step-by-step explanation:
Let <em>X</em> = number of soldiers killed by horse kicks in 1 year.
The random variable .
The probability function of a Poisson distribution is:
(a)
Compute the probability of more than one death in a corps in a year as follows:
P (X > 1) = 1 - P (X ≤ 1)
= 1 - P (X = 0) - P (X = 1)
Thus, the probability of more than one death in a corps in a year is 0.1252.
(b)
The average deaths over 7 year period is:
Compute the probability of no deaths in a corps over 7 years as follows:
Thus, the probability of no deaths in a corps over 7 years is 0.0130.
