Question

from the set of cards numberd from 1 to 30, one card is drawn randomly .find the probability of getting a card divisible by 5 or 7​.....plz solve it....

Answer 1

Step-by-step explanation:

sample space is equal to S

n(s)= (1,2,3.......30)

n(s)=30

let a be the event that the number is divisible by 5

(A)= (5,10,15,20,25,30) n(a)=6

p (a) =n(a)/n(s)

=6/30

=1/5

let event b be the event that the number is divisible by 7

B=(7,14,21,28)

n(b)=4

p(b) =n(b)/n(s)

= 4/30

= 2/15
