The sample space consists of 24=16 outcomes.
A. more tails than heads:
1. exactly three tails:
TTTH TTHT THTT HTTT
2. exactly four tails:
TTTT
So calculate the probability.
You can try in a similar way to solve the second part.
Four coins are tossed. What is the probability of getting more tails than heads and getting at least two heads?
