Question 1137711
exactly 2 is 10C2(.33^2)(.67*8)=0.1990
1 would be 10*.33*.67^9=0.0898
0 would be 0.0182
so more than two would be 1- probability (0 and 1 and 2)=0.693

3 would be 10C3*0.33^3*0.67^7=0.2614
4 would be 10C4*0.33^4*0.67^6=0.2253
5 would be 0.1332
2 and 5 inclusive is the sum of four terms=0.8189
