1. What is the median value?

2. Let event B = Odd number and let event C= Less than the median

Calculate P(B I C) as a fraction in lowest term.

Calculate P(C I B) as a fraction in lowest terms.

Answer 1

( 1 )

The median is the middle number in a sorted list of numbers. So, to find the median, we need to place the numbers in value order and find the middle number.

Ordering the data from least to greatest, we get:

20   27   33   34   37   39   41   44   47   50   58   60   61   61   67   71   73   73   74   76   78   82   84   88.   88   

So, the median is 61 .
