Explanation / Answer

1)expected count =150/3 =50

option 50 is correct

2) degree of freedom =(number of rows-1)*(number of columns-1) =(4-1)*(5-1)=12

3)

degree of freedom =number of categories-1 =5-1 =4

4)

applying chi square goodness of fit test:

from above test statisitic =2.09

5)

from above chi statisitc =4
