Types of Probability
In Probability theory, it can broadly be classified into 2 types as follows:
- Experimental Probability
- Theoretical Probability
Let’s understand these types in detail.
Experimental Probability
In the 9th class, we studied experimental probability. Experimental probability is the probability, which tells the possible outcomes, after performing an experiment. For example, if you toss a coin 50 times, then we could have different outcomes, in repeating experiments i.e. for experiment 1, the number of heads = 23, and the number of tails = 27, for experiment 2, the number of heads = 26, and a number of tails = 24, and so on… Here, if we find the probability of getting a head, it will be nearer to 0.5, but not exactly will be equal to 0.5.
Below is the formula for calculating experimental probability:
Probabitlity = number of required outcomes after performing an experiment / total number of times experiment performed
Theoretical Probability
In this chapter, we will be studying theoretical probability in detail. Theoretical probability, tells how likely an event is going to occur, and in these events, we will only be assuming what can be the possible outcomes, but will not be performing experiments. For example, as we have seen above in the coin example, the experimental probability of getting a head/tail is near 0.5, but not exactly equal to 0.5, but theoretical probability, says that the probability of getting a head/tail is equal to 0.5, as head and tail are equally likely outcomes. Theoretical probability is also called classical probability.
Below is the formula for calculating theoretical probability:
P(E) = Number of trials in which an event occured/ total number of trials
