Question

If A = [ prime numbers less than 20 ] and B = [ whole numbers less than 10 ] then [A - B ] Union [ B - A ] = ?

Answer 1

Answer:

A-B=(11,13,17,19)

B-A=(0,1,4,6,8,9)

Step-by-step explanation:

A=(2,3,5,7,11,13,17,19)

B=(0,1,2,3,4,5,6,7,8,9)

A-B =(2,3,5,7,11,13,17,19)-(0,1,2,3,4,5,6,7,8,9)

A-B= (11,13,17,19)

B-A=(0,1,4,6,8,9)
