Answer:

1/221 or 0.005

Explanation:

• The number of aces in a standard 52-cards deck = 4

,

• The total number of cards = 52

The probability of drawing two cards (Aces) without replacement is given below:


\begin{gathered} P(1st\text{ Ace)}=(4)/(52) \\ P(2nd\; \text{Ace)}=(3)/(51) \end{gathered}

Therefore, the probability that all cards are aces is:


\begin{gathered} P(\text{all aces)}=(4)/(52)*(3)/(51)=(1)/(221) \\ \approx0.005 \end{gathered}

The probability is 1/221 (as a fraction) and 0.005 (as a decimal correct to 3 decimal places).
