Questions: What is the probability that a randomly selected individual 15 years or older was involved in Complete Parts (a) through (f) below.

Solution Steps

To find the probability that a randomly selected individual 15 years or older was involved, we need to sum up the given probabilities for each part. This involves simply adding the provided probabilities.

The probabilities provided for the different parts are: \[ P_0 = 0.235, \quad P_1 = 0.127, \quad P_2 = 0.122, \quad P_3 = 0.024, \quad P_4 = 0.004, \quad P_5 = 0.001 \]

To find the total probability that a randomly selected individual 15 years or older was involved, we sum all the given probabilities: \[ P_{\text{total}} = P_0 + P_1 + P_2 + P_3 + P_4 + P_5 \] Substituting the values: \[ P_{\text{total}} = 0.235 + 0.127 + 0.122 + 0.024 + 0.004 + 0.001 = 0.513 \]
