The first two are fairly standard (I)GCSE fare but subsequent questions become more complex with questions 5 and 6 requiring the solution of quadratic equations if an algebraic approach is used. WebAug 19, 2024 · Following is a tree diagram for this situation. The branches are labeled with probabilities instead of frequencies. The numbers at the ends of the branches are calculated by multiplying the numbers on the two corresponding branches, for example, ( 3 11) ( 2 10) = 6 110. Figure 10.6. 3: Total = 56 + 24 + 24 + 6 110 = 110 110 = 1.
