One coin and one die are thrown simultaneously. Condition for event A: To get a head and an odd number. Condition for event B : To get a head or a tail and an even number. Condition for event C : Number on the upper face is greater than 7 and tail on the coin. |
Answer» The sample space (for a coin) `S={H,T}" "thereforen(S)=2.` The sample space (for a die) `S=(1,2,3,4,5,6)" "thereforen(S)=6` if a coin is tossed and a die is thrown simultaneously, the sample space `S={H1,H2,H3,H4,H5,H6,T1,T2,T3,T4,T5,T6}` `thereforen(S)=12` (i) Condition for event A : To get a head and an odd number. `thereforeA={H1,H3,H5}` `thereforen(A)=3." "....(2)` Condition for event B : To get a head or tail and an even number. `thereforeB={H2,H4,H6,T2,T4,T6}` `thereforen(B)=6." "...(3)` (iii) Conditon for event C : Number on the upper face is greater than 7 and tail on the coin. There is no number greater than 6 on a die. `thereforeC=phi` `thereforen(C)=0." "...(4)` |
