    Combinations

    A history exam paper contained 8 questions. 4 from Part A and 4 from Part B. Candidates are required to attempt 5 questions. In how many ways can this be done if at least 2 questions from Part A and at least 2 questions from Part B must be chosen.

    So, what I did was,

    2(4C3*4C2)= 48

    So, i wanna ask, is my approach correct ??

    Please Help !
