Question:

The probability distribution for the random variable x follows.

x f(x)
20 0.23
24 0.14
30 0.30
36 0.33
  1. Is this a valid probability distribution?
    SelectYes, because all f(x) are ≥ 0 and sum of f(x)=1Yes, because all f(x) are ≤ 0 and sum of f(x)=1Yes, because all f(x) are ≥ 0 and sum of f(x)>1Yes, because all f(x) are = 0 and sum of f(x)=1Item 1
  2. What is the probability that x = 30 (to 2 decimals)?

  3. What is the probability that x is less than or equal to 24 (to 2 decimals)?

  4. What is the probability that x is greater than 30 (to 2 decimals)?
