How to Find Probabilities for Z with the Z-Table - dummies

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 WebFind the probability that she makes her first free-throw, then misses the second, and then makes her third free-throw.
