A discrete random variable X can only assume the values of 0, 1, 2 and 3.Given that 𝑃(𝑋 ≥ 2) = 0.6 , 𝑃(𝑋 ≤ 2) = 0.85Determine 𝑃(𝑋 = 2)
Question
Solution 1
To find the probability that X = 2, we can use the given probabilities P(X ≥ 2) and P(X ≤ 2).
P(X ≥ 2) is the probability that X is either 2 or 3. P(X ≤ 2) is the probability that X is 0, 1, or 2.
Since these two events overlap at X = 2, we can find P(X = 2) by subtracting the probability of the o Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
