1. Answer:

   { 0,1,2,3,4,5,6}

   Step-by-step explanation:

   A={ x : x∈ W, x≤ 5}

   Thus A= { 0,1,2,3,4,5}

   B={ x : x is a prime number less than 5}

   B={ 2,3}

   U ={ x : x is an integer, 0 ≤x ≤ 6

   U={ 0,1,2,3,4,5,6}

   Now B-A= { } ( blank set)

   We know that

   (B-A)’=U-(B-A)

   =U -{}

   =U={ 0,1,2,3,4,5,6}
