These are dependent events.....the second card that is drawn is dependent upon the card that is drawn first  [Hint....any time we have "without replacement"....the event will be dependent ]

 

Second one

We have 13 Hearts.....the probability that one of them is a King  is just  1/13

 

Last one

 

We have a total of  70 + 50  = 120  students who arrived by car

 

The probability that  one of these is a girl  is   

 

[ Number of girls that arrived by  car  ]  /  [ Total Arrivals by car ]  =

 

[ 50  / 120 ]   =  5/12  ≈    .42  =   42%
