In a normal deck there are 39 such cards. There is one 9 of clubs in a deck of cards. There are two red aces in a deck of cards. There are 26 red cards in a deck of 52 cards. How many 2 of hearts are in a deck of cards? Is that the question? If it is then the answer is 1. There is only one 2 of hearts in a deck of cards.

Empirical Definition of Probability. The probability of event A is the number approached by.

The idea that the fraction in the previous definition will approach a certain number as the total number of recorded outcomes becomes very large is called the Law of Large Numbers. Because of this law, when the Classical Definition applies to an event A , the probabilities found by either definition should be the same. In other words, if you keep rolling a die, the ratio of the total number of twos to the total number of rolls should approach one-sixth.

In working with the empirical definition, most of the time you have to settle for an estimate of the probability involved.

This estimate is thus called an empirical estimate. Example 4 To estimate the probability of a licensed driver in Louisiana being involved in an auto accident this year, you could use the ratio. To do better than that, you could use the number of accidents for the last five years and the total number of Louisiana drivers in the last five years. Or to do even better, use the numbers for the last ten years or, better yet, the last twenty years. Example 5 Estimating the probability of rain tomorrow would be a little more difficult.

You could note today's temperature, barometric pressure, prevailing wind direction, and whether or not there are rain clouds that could be blown into your area by tomorrow. Then you could find all days on record in the past with similar temperatures, pressures, and wind directions, and clouds in the right location. Your rainfall estimate would then be the ratio.

To make your estimate better, you might want to add in humidity, wind speed, or season of the year. Or maybe if there seemed to be no relation between humidity levels and rainfall, you might want add in the days that did not meet your humidity level requirements and thus increase the total number of days.

Example 6 If you want to estimate the probability that a dam will burst, or a bridge will collapse, or a skyscraper will topple, there is usually not much past data available. There are 4 sevens in a deck of 52 cards. If you mean a deck of cards, then there are 4 queens in total. In a deck of cards there are 4 suites: 1 diamonds 2 hearts 3 spades 4 clubs. There are four 2s in a standard deck of playing cards. In a deck of cards there are the same number of cards for every suit. In a standard deck there are 52 cards and 4 suits.

Dividing 52 cards by 4 means there are 13 of each suit, which includes hearts. Log in. Card Games. Study now. See Answer. Best Answer. Study guides. Q: How many 4 are in a deck of cards?
