The discrete random variable X has the given probability distribution. x 1 2 3 4 5 P(X = x) 0.2 0.25 0.4 A 0.05
Added by Najaf A.
Step 1
We know that the sum of all probabilities must equal 1. Therefore, we can use this fact to find the missing probability: 0.2 + 0.25 + 0.4 + A + 0.05 = 1 Simplifying this equation, we get: A = 0.1 Therefore, the missing probability is 0.1. Show more…
