Answer to Problem 49E
The probability of selected all three numbers less than or equal to 3 is
Explanation of Solution
Given information:
A random number generator selects three numbers from 1 through 10.
All three numbers are less than or equal to 3.
Calculation:
Consider the 1 to 10 numbers. Three numbers randomly selected from 1 to 10 numbers.
There are total 3 numbers less than or equal to 3, so probability of selecting one number less than equal to 3 is,
Since, the selection of all three numbers is independent events.
So, the probability that the selected three numbers less than or equal to 3 product of individual probability of selecting one number,
Hence, the probability of selected all three numbers less than or equal to 3 is
