A coin is tossed. What is the probability of getting:
a head?
उत्तर
On tossing a coin once,
Number of possible outcome = 2
a head
Similarly, Favourable outcome of getting a head = 1
But the number of possible outcomes = 2
∴ P(E) = `"Number of Favourable outcome"/"Number of all possible outcome"`
= `1/2`
