Question

If A = { Prime numbers less than 10 }, and B = { Positive odd numbers less than 10 }, then fin i) An B ii) B-A​

Answer 1

Answer:

1) A = {2, 3, 5, 7}

B = {0, 2, 4, 6, 8}

2) B - A = {0, 2, 4, 6, 8} - {2, 3, 5, 7} = 5 - 4 = 1

Answer 2

Answer:

9i) A ∩ B= {3,5,7} (ii) B-A

Step-by-step explanation:

Given data:

• A = { Prime numbers less than 10 }

• B = { Positive odd numbers less than 10 }

• Prime numbers less than $10$ are $2,3,5,7$.

• Positive odd numbers less than $10$ are $1,3,5,7,9$

(i) $A$∩$B$ $=$ { $3,5,7$ }

(ii) $B-A=$ {$1,9$ }
