A diagram has the events as nodes and the probabilities as branches. There are two branches from the root. The first branch, labeled $0\mathrm{.}634,$ leads to node D$.$ There are two branches from this node. The first branch, labeled $0\mathrm{.}226,$ leads to node $T.$ There are two branches from node $T.$ The first branch, labeled $0\mathrm{.}455,$ leads to node B$.$ The second branch has an empty label. This branch leads to node B with an apostrophe. The second branch from node $D$ has an empty label. This branch leads to node $T$ with an apostrophe. There are two branches from this node. The first branch, labeled $0\mathrm{.}378,$ leads to node $B.$ The second branch has an empty label. This branch leads to node B with an apostrophe. The second branch from the root has an empty label. This branch leads to node $L.$ There are two branches from this node. The first branch has an empty label. This branch leads to node T$.$ There are two branches from node $T.$ The first branch, labeled $0\mathrm{.}895,$ leads to node $B.$ The second branch has an empty label. This branch leads to node B with an apostrophe. The second branch from node L$,$
