Question

The following table presents the probability distribution of the number of vacations X taken last year for a randomly chosen family. Find P1 or more. 0.63 0.72 0.28 0.91

Answer 1

To find P(1 or more), add the probabilities of all values that are 1 or more from the given probability distribution.

Step-by-step explanation:

To find P(1 or more) from the given probability distribution, we need to add up the probabilities of all the values that are 1 or more. Looking at the table, the probabilities of the values that are 1 or more are 0.63, 0.72, and 0.91. So, to find P(1 or more), we add these probabilities:

P(1 or more) = 0.63 + 0.72 + 0.91 = 2.26
