We come across probability in our daily life and use it all the time, usually without thinking of it. Everything from the weather forecasting to our chances of being died in an accident is a probability.
Probability is a mathematical term for the likelihood that something will occur. It is the ability to understand and estimate the likelihood of any different combination of outcomes.
Let’s discuss some real-life examples of Probability
1. Weather Forecasting
Before planning for an outing or a picnic, we always check the weather forecast. Suppose it says that there is a 60% chance that rain may occur. Do you ever wonder from where this 60% came from? Meteorologist uses a specific tool and technique to predict the weather forecast. They look at all the other historical database of the days those have similar characteristics of temperature, humidity, and pressure, etc. and determine that on 60 out of 100 similar days in the past, it has rained.
2. Batting Average
Batting average represents how many runs or scores a player will make before getting out. For examples, a football player has made 10 out of 20 goals from over 50 yards. Then he would have the batting average of 50% chances to make a goal in the next match from that yard.
3. Typing on a smart device
We all have smart devices, and they have software of suggesting words. When we start typing the word, our device immediately displayed the most searched word using probability just by guessing the initial alphabets of that word.
4. Flipping a coin or Dice
Flipping a coin is the easiest way of tossing a match. There is no surety either head will come or not. Both head and tails have 1 out of 2 i.e., 50% chances to occur. Hence, the probability of getting the desired outcome is 0.5. Similarly while playing with dice, there are 1 out of 6 chances, that the required number will come.
Probability helps in analyzing the best plan of insurance which suits you and your family. For example, You are an active smoker, and chances of your getting lungs disease are higher. Also nowadays people are getting their mobile phones getting insured because they know that their chances of getting damage or loss are high.
6. Are we likely to die in an accident?
Rates of car accidents have increased rapidly in the past decades. For example, if a city has a population of one lakh and the death rate in car accidents is 500. so the chance of being killed in an accident is 500/1 lakh is 0.05%. So clearly a person has 0.05% chances to die in a car accident.
7. Lottery Tickets
winning or losing a lottery is also an example of probability. In a typical Lottery game, each player chooses six distinct numbers from a particular range. If the six numbers on a ticket match the numbers drawn by the lottery, the ticket holder is a Jackpot winner- regardless of the order of the numbers. The probability of this happening is 1 in around 10 lakh.
8. Playing Cards
There is a probability of getting a desired card when we randomly pick one out of 52. for example, The probability of picking up an ace in a 52 deck of cards is 4/52 since there are 4 aces in the deck. The odds of picking up any other card is therefore 52/52 – 4/52 = 48/52.
