The sets A = {b, c, d, e} and B = {x: x is a letter in the word "master"} are jointGroup startsTrue or FalseTrue, unselectedFalse, unselected

To determine if the sets A = {b, c, d, e} and B = {x: x is a letter in the word "master"} are joint, we need to check if they have any elements in common.

1. Set A contains the elements {b, c, d, e}.
2. Set B is defined as the set of letters in the word "master". The letters in "master" are {m, a, s, t, e, r}.

To check if the sets are joint, we compare their elements:

1. The element 'b' is present in set A.
2. The element 'm' is not present in set A.
3. The element 'a' is not present in set A.
4. The element 's' is not present in set A.
5. The element 't' is not present in set A.
6. The element 'e' is present in set A.
7. The element 'r' is not present in set A.

Since set A and set B have the elements 'b' and 'e' in common, we can conclude that the sets are joint.
