You pick a card at random. Without putting the first card back, you pick a second card at random. 4 ,5, 6 .7 What is P(4, 4)? Simplify your answer and write it as a fraction or whole number.
Is the list of cards, 4,5,6,7 as you have written?
If so, the probability of P(4, 4) would be 0%. The problem states that once a card is drawn, it is not replaced. Therefore, there would be no way possible to draw 2 4's.
