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%
