Question

an integer is chosen at random from the first 50 integer .what is the probability that the chosen integer is diviaible by 5

Answer 1

Favourable outcomes=5,10,15.....50
No. Of terms=10
Total outcomes=50
Therefore required probability=10/50
1/5

Answer 2

integers are from -∞ to ∞ so it is not possible to tell the probability as there is no such term as 'first 50 integers'
