- Prove that the following version of a greedy algorithm produces a minimum spanning tree in aweighted graph. Start with a vertex v as the initial tree and at each stage add an edge with minimumweight having exactly one end in the current tree.

If all four numbers come up then you win $72 for each dollar you bet. If three numbers come up then you win $5 for each dollar you bet. If two numbers come up then you win $1 for every dollar you bet (net winnings are zero). Otherwise, you lose the money you bet. Fill out the following table, assuming a $1 bet. Enter your probabilities as decimals, entering all the digits you see on your calculator.
