How do I find out 4)?

Step-by-step explanation:

Given expression is,

By dividing denominator and numerator of the given fraction by m²,

=

We know that

Therefore, We can evaluate the limit of the expression by substituting ∞ in for m.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
