Answer:
![\frac{4}{52} \times \frac{4}{51} = \frac{16}{2652} = 0.00603 = 0.603\%](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B52%7D%20%5Ctimes%20%5Cfrac%7B4%7D%7B51%7D%20%20%3D%20%5Cfrac%7B16%7D%7B2652%7D%20%3D%200.00603%20%3D%200.603%5C%25)
Step-by-step explanation:
There are 52 cards in a standard deck, and there are 4 suits for each card. Therefore there are 4 twos and 4 tens.
At first we have 52 cards to choose from, and we need to get 1 of the 4 twos, therefore the probability is just
![\frac{4}{52}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B52%7D)
After we've chosen a two, we need to choose one of the 4 tens. But remember that we're now choosing out of a deck of just 51 cards, since one card was removed. Therefore the probability is
![\frac{4}{51}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B51%7D)
Now to get the total probability we need to multiply the two probabilities together
![\frac{4}{52} \times \frac{4}{51} = \frac{16}{2652} = 0.00603 = 0.603\%](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B52%7D%20%5Ctimes%20%5Cfrac%7B4%7D%7B51%7D%20%20%3D%20%5Cfrac%7B16%7D%7B2652%7D%20%3D%200.00603%20%3D%200.603%5C%25)
