Question

.Find the cardinal number of the following set. A= { p : p ∈ W and 2p - 3 < 8​

Answer 1

Step-by-step explanation:

Given :

• 2P – 3 < 8

Find :

• The cardinal number of the set

Solution :

Adding 3 to both sides, we get

→ 2P – 3 + 3 < 8 + 3

→ 2P < 11

Dividing both sides by 2, we get

→ P< 11/2

→ P< 5.5

∴ A3 = {0,1,2,3,4,5}

Hence :

The number of elements in the set A3 is 6.

∴ Cardinal number of set A3 = 6.
