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 dependent.

Explanation

Total sample space `S=2^3={(HHH), (HHT), (HTH), (HTT), (THH), (THT), (TTH), (TTT)}`


`n(S)=8`


Event `A`: two heads appear


`A={(HHT), (HTH), (THH)}`


`n(A)=3`


`P(A)=3/8`


Event `B`: last should be head


`B={(HHH), (HTH), (THH), (THH)}`
