WebWe know that the probability P(X > 75) is equal to 1 – P(X ≤ 75), so we can use a table to find P(X ≤ 75). This result is equal to P(Z ≤ 0.5) (where Z is the standardized random variable). The table states that P(Z ≤ 0.5) = 0.6915 Now we can calculate P(X > 75). P(X > 75) = 1 – P(X ≤ 75) = 1 – P(Z ≤ 0.5) = 1 – 0.6915 = 0.3085 WebMar 26, 2024 · The probability of an event A is the sum of the probabilities of the individual outcomes of which it is composed.
