Question

Tickets are numbered from 1 to 100. They are well shuffled and a ticket is drawn at random. What is the probability that the drawn ticket has a number, multiple of 7? 7

Answer 1

Total outcomes = 100

Favourable outcomes = 7,14,21,28,35,42,49,56,63,70,77,84,91,98

= 14

P( a multiple of 7) = 14/100

= 7/50

Answer 2

1. number cards are 1 to 100
2. The multiples of 7 btw 1 to 100 are :-7,14,21,28,35,42,49,56,63,70,77,84,91,98and that's it
3. so there are total 14 multiples
4. so the probability =favourable outcome /total outcomes
5. i . e. 14/100=7/50
