Solve the problem.

A firm uses trend projection and seasonal factors to simulate sales for a given time period. It assigns $"0"$ if sales fall, $"1"$ if sales are steady,

$"2"$ if sales rise moderately, and $"3"$ if sales rise a lot. The simulator generates the following output.

$0102000103200002123120203002101$

Estimate the probability that sales will rise moderately.
