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 |
