chi squared/pearson squared problem

A computer package counts the total number of "leg before wicket" decisions make by umpires in each session of a number of test matches. The results are shown in the table below.Number of lbw decisions, x Number of sessions with x lbw decisions

0= 21

1= 19

2= 11

3 or more= 7

If using the χ2 goodness-of-fit test to determine whether the observations come from a Poisson distribution with mean 1.2, calculate the value of Pearson's X2 statistic, correct to 2 decimal places
