Suppose we have the following statements
- Sun rises from the west
- Ganga is the river in India
India will win the test match
Statement 1 is always false.
as Sun rises from the east
Statement 2 is always true.
as Ganga is a river in India
Statement 3 is not always true or false.
India can win the match or not. Both are possible.
In statement 3, we can try to find the chance where India can win
Let’s look at Chance & Probability
Suppose we toss a coin 25 times.
Our result can be something like
Chance of Tail Coming = (Total number of times Tail has come)/(Total number of outcomes)
Chance of Head Coming = (Total number of times Head has come)/(Total number of outcomes)
Chance is defined by the result of outcomes.
But, what if we toss the coin
or 10000 times
or Infinite times?
Assuming the number of outcomes is infinite,
then chance becomes Probability
we can do for a die
A die is thrown 250 times, whose outcomes are represented below. What will be the probability of getting 5?
Chance of getting 5 = 38/250
Suppose we toss a coin,
there are only 2 possible outcomes − Heads or Tails
Probability of getting Head
= (Number of outcome where head can come)/(Total possible outcomes numbers)
Probability of getting Tail = 1/2
Similarly for Die,
Probability outcomes = 1, 2, 3, 4, 5, 6
Probability of getting 5
= (Number of outcome where 5 can come)/(Total possible outcomes numbers)
Probability of getting 7 = 0/6
Probability of getting number less than or equal to 6 = 6/6
