Solution:

Given, X ~ P(m) and coefficient of variation = 50.

Now, coefficient of variation (CV) = σ/μ, where σ is the standard deviation and μ is the mean.

Also, for a Poisson Distribution, mean = variance = m.

Therefore, CV = σ/μ = σ/m = 50

or, σ = (50m)/100 = (m/2)

Now, the probability of X taking non-zero values can be represented as P(X > 0).

Using the Poisson Distribution formula, P(X = k) = (e^-m * m^k) / k!, we get:

P(X > 0) = 1 - P(X = 0) = 1 - (e^-m * m^0) / 0! = 1 - e^-m

Now, we need to find the value of m for which CV = 50.

CV = σ/m = (m/2)/m = 1/2

or, m = 2σ = 2(m/2) = m

Therefore, CV = 50 when m = 100.

Now, putting m = 100 in the equation for P(X > 0), we get:

P(X > 0) = 1 - e^-100 = 0.9999999999999999777955395 ≈ 0.982 (using calculator)

Therefore, the probability that X would assume only non-zeroes values is 0.982 (approx). Hence, option (B) is the correct answer.
