QUESTION
The probability distribution for the random variable x follows . X F ( X ) 20 0 . 21 24 0. 16 31 0 . 28 37 0 . 35 a . Is this a valid probability
three questions attached
- Is this a valid probability distribution?
- Select
- Yes, because all f(x) are ≥ 0 and sum of f(x)=1
- Yes, because all f(x) are ≤ 0 and sum of f(x)=1
- Yes, because all f(x) are ≥ 0 and sum of f(x)>1
- Yes, because all f(x) are = 0 and sum of f(x)=1
- Item 1
- What is the probability that x = 31 (to 2 decimals)?
- What is the probability that x is less than or equal to 24 (to 2 decimals)?
- What is the probability that x is greater than 31 (to 2 decimals)?
