so the sum TRIc-3) is mean the situation of the Gearge's acount
after the two transactions today
Gerge is bank account cared 44 today
Total possible outcomes: (2)³=8 (heads or tails possibility on each toss)
Draw out a Tree diagram to illustrate the given example, labelling the probability on each branch.
Adding all the possible situations with P(t)≥2, we get 0.352 as the probability.
Hope I helped :)
