In a single throw

Answer :

(i) A coin has two sides a head(H) and a tail(T), and there are two such coins.


There are Xm possible outcomes.


That is 22 = 4 and they are HH, HT, TH, TT


All possible outcomes are HH, HT, TH, TT.


Total number of outcomes = 4


Chances of getting 2 tails = 1, that is TT


Probability P() =


Probability of getting a tail P(both T) = =

All possible outcomes are HH, HT, TH, TT.


Total number of outcomes = 4


Chances of getting atleast one tail = 3, that is HT, TH, TT.
