Question

If the probability distribution is 1/10, 1/5, 1/2, x, what is the value of x? A. 1/5 b. 1/10 c. 3/10 d. 3/5

Answer 1

the answer in simple terms is A.1/5

Answer 2

You would make them all over 10, then subtract them from
`(10)/(10)`
The probabilities are
`(1)/(10), (2)/(10), (5)/(10)`
Add them together, you get,
`(8)/(10)`

`10-8=2` so
`x=(2)/(10) or (1)/(5)`
