KCSE 2021 PROBABILITY QUESTION.

[@1Healthmatters]

Number of students should be 200

[@shiftinggrades]

Okay

[@monicahwangoi2296]

Part b should be p(f1,f4)+p(f4,f1) if you sum them you will get 24/199
ii) p(f4,f1,wears glasses)=21/9950

[@shiftinggrades]

Thank you

[@fokokoster]

Kindly check part b.., once the first student is picked the number reduces by 1, that is picking without replacement.

[@shiftinggrades]
