Answer» 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

Answer»

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

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

=>2/5(12-7)

=>2×5/5
