Answer #1

Assuming the probability distribution function is symmetrically distributed about mean value 0.

For k>0, n>=2 and n is an integer.

The cumulative probability for ,

...(1)

i.

The probability distribution is symmetrically distributed about 0,

Therefore,

ii.

(From (1))

Since the area under the probability distribution curve is unity.

So,
