(a) o
(b) 7
(c) 5

Answer 1

Answer:

answer for the given problem is given

A={ month of a year}

=>A={Jan,Feb,mar, April,may,June,July,aug,sep,Oct,Nov,Dec}

=>n(A)=12

B={day in a week}

=>B={sun,mon,Tue,wed,thu,Fri,sat}

=>n(B)=7

now the value of 2[n(A) - n(B)]

=>2[12-7]

=>2(5)

=>10

The value of 2[n(A) - n(B)]=10

or you gave like 2/5[n(A) - n(B)]

=>2/5(12-7)

=>2×5/5

=>2
