Question
A coin is tossed once. What is the probability of getting a tail?
Solution 1
When a coin is tossed once, the possible outcomes are H and T.
Total number of possible outcomes = 2
Favourable outcome = 1
∴ Probability of getting a tail = P (T)
=`"Number of favourable outcomes"/"Total number of possible outcomes" = 1/2`
Solution 2
Sample space (S) = {H, T}
∴ n(S) = 2
Event (E) = {T}
∴ n(E) = 1
P(E) = `"n(E)"/"n(s)" = 1/2`.
