Question

The probability of a component's failure is 0.05. Out of 14 components what is the probability distribution of X.
hint:binomial distribution​

Answer 1

A study was conducted to find out the concentration of sulphur dioxide in the air in parts per million (ppm) of a certain city. The data obtained for 30 days is as follows:

0.03

0.16

0.11

0.08

0.11

​  

 

0.08

0.05

0.08

0.01

0.07

​  

 

0.08

0.02

0.12

0.10

0.05

​  

 

0.09

0.06

0.13

0.06

0.07

​  

 

0.04

0.18

0.22

0.09

0.01

​  

 

0.17

0.20

0.07

0.18

0.04

​  

 

(i) Make a grouped frequency distribution table for this data with class intervals as 0.00−0.04,0.04−0.08, and so on.

(ii) For how many days, was the concentration of sulphur dioxide more than 0.11 parts per million?
