Question

A randomized controlled experiment studied three police responses to spousal abuse: 1) advise and possibly separate the couple, 2) issue
a citation to the offender, and 3) arrest the offender. The effectiveness of the three responses was determined by re-arrest rates. The table
in photo shows the rates. 

We want to test the null hypothesis that the proportions of subsequent arrests are the same regardless of the treatment
assigned. Under the null hypothesis, help me determine the expected number of times no subsequent arrest would occur for the treatment
“Advise/separate”?
