Question

04-1f n = 36 x 21 x 35, then which of the following is not an integer. A. n/45 B. n/14 LE. n/24 b. n/49​

Answer 1

Answer:

29

Step-by-step explanation:

X={x:1≤x≤50,x∈N}

A={x:x is multiple of 2}

∴n(A)=25

B={x:x is multiple of 7}

∴n(B)=7

n(A∩B)=3

From question

n(A∪B)=n(A)+n(B)−n(A∩B)

=25+7−3

=29
