Consider the probability density f(x) = ae-b|x| where x is a random variable whose allowable values range from x = - ∞ to x = + ∞. P(1 ≤ x ≤ 2)

Q: Consider the probability density f(x) = ae-b|x| where x is a random variable whose allowable values range from x = - ∞ to x = + ∞. P(1 ≤ x ≤ 2)

P(x) = ae-b|x|dx to get apply aebxdx + ae-bxdx, we get = .

(e-b - e-2b)

Correct Answer:

Explanation:

P(x) = ae^-b|x|d_x

to get apply ae^bxdx + ae^-bxd_x,

we get = .
