Probability is 12\frac{1}{2}21 for Heads on the first toss.
Multiply probabilities along the branches.
Depends on the total red and overall balls in the draw.
Used for multiple events where outcomes affect others.
It shows likelihood of events given prior outcomes.
P(A∣B)=P(A∩B)/P(B)P(A|B) = P(A \cap B) / P(B)P(A∣B)=P(A∩B)/P(B) when P(B)≠0P(B) \neq 0P(B)=0.
Probability of HT is 14\frac{1}{4}41 or 0.250.250.25 from tossing twice.
