In a survey of 400 youngsters aged 16-20 years, it was found that 191 have their voter ID card. If a youngster is seceted at random, find the probability that the youngster does not have their voter ID card
Text Solution
Verified by Experts
No. of youngsters n(S) = 400 No. of youngsters having voter id n(A) = 191 No. of youngsters do not have their voter id n(B) = 400 - 191 = 209 `P(B) = (n(B))/(n(S)) = (209)/(400)`
