if one card is drawn from a normal pack of 52 playing cards,what is the probability of getting a king or a heart?
how many kings ?
how many hearts ?
remember not to count the king of hearts twice, it would be included in both counts.
To find the probability of getting a king or a heart when one card is drawn from a standard deck of 52 playing cards, you need to determine the number of favorable outcomes (cards that are either a king or a heart) and divide it by the total number of possible outcomes.
Number of favorable outcomes:
There are 4 kings in a standard deck (one king for each suit), and there are 13 hearts in a deck (one heart for each rank). However, there is one king that is also a heart. So, the number of favorable outcomes is 4 (kings) + 13 (hearts) - 1 (king of hearts) = 16.
Total number of possible outcomes:
A standard deck of 52 playing cards has 52 cards in total.
Probability:
The probability of an event occurring is the number of favorable outcomes divided by the total number of possible outcomes. In this case, the probability is 16/52, which can be simplified to 4/13.
Therefore, the probability of drawing a king or a heart from a standard deck of 52 playing cards is 4/13.
