Question

A number is selected from the numbers 2,3,3,5,5,5,7,7,7,9,9,9,9,9 at random find the probability that the number selected is (1)their median (2)their mode​

Answer 1

Answer:

1: 1/14

2: 5/14

Step-by-step explanation:

There are 14 terms in total ,their median:

n/2

=14/2

=7th term which is 7

therefore , p(median)=1/14

and

mode = observation with highest frequency:

9(occured 5 times)

probability =

$\frac{number \: of \: observations \: favourable}{total \: observations}$

=5/14
