Historically, the probability of a successful steal of a second base is 68% and being thrown out is 32%. Suppose there is a runner on first base. For each possible number of outs, determine whether is it advisable to have the runner attempt to steal second base.

Probability of scoring any runs

0 outs - .39
1 out - .26
2 outs - .13

so for each the probability of not scoring is .61, .74, and .87.
can someone help me determine if these are advisable? Thanks
