A box contains 14 mangoes out of which 6 are spoilt. If six mangoes are chosen at random, find the probability that A number is selected at random from first fifty natural numbers. What is the chance that it is a multiple of either 5 or 12?  Answers:	A) 15/25	B) 2/25	C) 14/25	D) 7/25	E) 7/50
The probability that the number is a multiple of 5 is 10/50. (Since 5*10=

50).   Similarly the probability that the number is a multiple of 12 is 4/50. {Since 14*4=   48).   Neither 5 nor 12 has common multiple from 1 to 50. Hence these events are mutually exclusive events. Therefore chance that the selected number is a multiple of 5 or 12 is (10+4)/50 = 7/25.   ANSWER:7/25
