Answer:
1/52
Step-by-step explanation:
The number of cards in a deck, N(cards) = 52
Number of diamonds in a deck, N(diamonds) = 13
Only one card is a ten and a diamond at the same time
Number of cards that is a ten and a diamond, N(ten AND diamond) = 1
Probability that the card is a ten AND a diamond
Pr(ten AND diamond) = N(ten AND diamond) / N(cards)
Pr(ten AND diamond) = 1/52
The probability that the card selected is a ten AND a diamond is 1/52
