Question

P= x/x is in multiple of 3 less than 30 then n (p)=?
1).10
2).9
3).8
4).11​

Answer 1

2) 9

Step-by-step explanation:

p denotes the multiples of 3 less then 30

hence,

p = { 3,6,9,12,15,18,21,24,27}

n(p) denotes the number of elements in p

hence , n (p) is 9

Answer 2

p = { 3,9,10,12,15,18,21,24,27}

n(p) = 9
