How many possibilities are there when you roll a die and draw a card from a standard deck of cards

Answers

a typical die has 6 faces, so there are 6 possibilities. a typical deck of cards contains 52 cards, so there are 52 possibilities.

Final answer:

The total number of possibilities when you roll a six-sided die and draw a card from a standard 52-card deck is 312.

Explanation:

The question is asking us to calculate the total possibilities when you roll a single six-sided die and draw a card from a standard 52-card deck. In mathematics, to calculate the total possibilities of two independent events happening together, we multiply the number of outcomes of the two events.

A six-sided die has 6 possible outcomes (1, 2, 3, 4, 5, or 6) and a standard 52-card deck has 52 possible cards to draw. Therefore the total possibilities, when you roll a die and draw a card, would be 6 (die outcomes) * 52 (card outcomes) = 312 total possibilities.
