Question

a number is selected at random from the numbers 2,3,3,5,5,5,7,7,7,7,9,9,9,9,9.
Find the probability that the selected number is
(1)their median (2) Their mode

Answer 1

First you have to find median and mode.
To find median:
Formula=n+1/2
==15+1/2
==14/2
= 7

Therefore for answer 1
Probability= no of given/total\
ANS 1= 7/15

Mode =9 because it has highest frequency
(It appears 5 times)
So probability=5/15
=1/5
ANS 2= 1/5
