Question

Philoid · Accepted Answer

(i) O

Total number students= 30

Number of students with blood group ‘A’ = 9

Number of students with blood group ‘B’ = 11

Number of students with blood group ‘AB’ = 4

Number of students with blood group ‘O’ = 6

Probability P() =

(i) Probability of selecting a student with blood group ‘o’

P(B) =

(ii) Probability of selecting a student with blood group ‘A’

P(B) =

(iii) Probability of selecting a student with blood group ‘AB’

P(B) =
