WebbYou multiply the fractions along the path or branch you follow. So HH = 1/2 x 1/2 or 1/4. This means the chance of getting HH is 0.25 or 25% or 1/4. The probability of TT is similar and by following the lower branches you get TT also having probabilities of 0.25 or 25% OR 1/4. The probability of getting a H and a T can be found looking at the ...

"WebbProbability: probability of ‘not’, ‘and’ and ‘or’ events. General addition rule applies to any additional events. You can use it for both disjoint events and non-disjoint events where two events are mutually exclusive. This means that if 1 event is true, the other must be false. Therefore, P (A and B), i.e. the probability of both ... " - Probability trees and or rule

Probabilities are listed at each endpoint and circled. These add up to 1 (or 100%) at each level of the tree. 2. The circled probability at a branch point is the sum of the circled probabilities at the ends of all branches coming out from it to the right. 3.
