A tree diagram has two stages. Stage $1$ has two nodes and stage $2$ has four nodes.

In stage $1,$ the branch from the starting position to node $A$ is labeled $0\mathrm{.}5.$ The branch from the starting position to node $B$ is an answer blank.

In stage $2,$ the branch from node $A$ to node $C$ is an answer blank. The branch from node $A$ to node $D$ is labeled $0\mathrm{.}5.$

In stage $2,$ the branch from node $B$ to node $C$ is labeled $0\mathrm{.}1.$ The branch from node $B$ to node $D$ is an answer blank.

Outcome
