Question

a number is chosen random from 1 to 9. the probability that it being prime is

Answer 1

hello mate,
total outcomes=1,2,3,4,5,6,7,8,9
favorable outcomes=2,3,5,7
so,probability= 4/9

Answer 2

Heya

Total number of outcomes = 9 { 1, 2, 3, 4, 5, 6, 7, 8, 9 }

Favourable outcomes of getting a prime number = 4 { 2, 3, 5, 7 }

P(x) = Favourable outcomes/Total outcomes

P( getting a prime number ) = 4/9

Hope this helps you.
