Question

Calculate the probability of winning: Draw a card from a standard deck of cards. You win if you draw a Queen or draw a Heart. Round answer to three decimal places.

Answer 1

To answer this question we will use the following expression to compute the probability that an event occurs:

`(FavorableOutcomes)/(TotalOutcomes).`

We know that there are a total of 52 cards in a standard deck, and there are 16 cards that are a Queen or a Heart, therefore the probability of choosing a Queen or a Heart is:

`(16)/(52).`

Simplifying the above result we get:

`(16)/(52)\approx0.308.`

Answer: 0.308.
