A coin is tossed three times. Event A:...

A coin is tossed three times.
Event A: two heads appear
Event B: last should be head
Then identify whether events A and B are independent or not.

Text Solution

Verified by Experts

The correct Answer is:
Not independent
`P(A)=3/8and P(B)=1/2`
`P(A)P(B) =3/8xx1/2=3/16`
`P(Annb)=2/8=1/4neP(A)P(B)`
Hence, A and B aer not independent.

Knowledge Check

  • Two events A and B will be independent, if

    A
    A and B are mutually exclusive
    B
    `P(A^(')B^('))=[1-P(A)][1-P(B)]`
    C

    D
    P(A) + P(B) = 1
