Answer:
The probability is 12/13.
Step-by-step explanation:
There are only 4 fours in the deck, and the total number of cards in the deck is 52.
Knowing that the probability of an event is given by the number of favourable cases divided by the total number of possible cases, we calculate the probability of being dealt every other card but a four by:
[tex]P(NotFour) = \frac{52-4}{52}=\frac{48}{52}[/tex]
[tex]P(NotFour) =\frac{12}{13}[/tex]
