Question

. P is the set of multiples of 6 less than 60 and Q is the set of multiples of 9 less than 60.Find n(P∩Q

Answer 1

Answer:

3

Step-by-step explanation:

Given,

P is a set of multiples of 6 less than 60 = { 6,12,18,24,30,36,42,48,54}

Q is a set of multiples of 9 less than 60 ={9,18,27,36,45,54}

P intersection Q = {18,36,54}

n(P intersection Q) = 3
