21Find the arithmetic mean of first ten natural numbers.0.12 A survey was conducted in a locality regarding the eating habits of persons. Out of450 persons, if 175 found to be pure vegetarian, then what is the probability ofperson selected at random of being non-vegetarian?

Answer»

Given, total number of person = 450

and, Number of vegetarians = 175

So, Number of non-vegetarians = 450 - 175 = 275

Therefore,

Probability of the person being non-vegetarian = (Number of non-vegetarians)/(Total number of person)

= 275/450

= 0.611

Hence, Probability of the person being non-vegetarian is 0.611.

GIVEN,THE TOTAL NO OF PEOPLES = 450NO OF PURE VEGETARIAN=175NO OF NON VEGETARIAN =450-175=275PROBABILITY =NO OF FAVOURABLE OUTCOMES/TOTAL NO OG OUTCOMESSO,PROBABILITY =275/450=O.611

0.611
