Question

(ii) Are the sets A (b, c, d, o) and B = (x:x is a letter in the word
"MASTER') disjoint ?​

Answer 1

$\huge\underline\mathtt\orange{Answer}$

A = {b , c , d , o }

B = {x : x is a letter in the word "MASTER"}

B = {m , a , s , t , e , r}

Yes, A and B are disjoint sets. Because no similarities between both sets.
