Answer:
1) All the possible outcomes
Tails followed by tails
Rails followed by heads
Heads followed by a tail
Heads followed by heads
2) Sample space
{(T,T), (T,H), (HT), (HH)}
3) Formula:
Using the above formula, we can compute the following probabilities.
Probability((T,T)) = 1/4
Probability((T,H)) =1/4
Probability((H,T)) =1/4
Probability((H, H)) =1/4
Probability(Atleast one tails) = 3/4
Probability(Atleast one heads) = 3/4
Probability(Exactly one tails) = 2/4
Probability(Exactly one heads) = 2/4
