Question

the table summarizes members of a local organization by age and whether they live east or west of the river. if a member of the organization is selected at random, what is the probability that the selected member is at least 40 years old? a) fraction 1 b) fraction 2 c) fraction 3 d) fraction 4

Explanation:

Step1: Identify relevant values

The number of members at least 40 years old is 107, and the total number of members is 138.

Step2: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So the probability $P = \frac{107}{138}$.

Answer:

The probability that the selected member is at least 40 years old is $\frac{107}{138}$.
