Question

P and Q are the subset of a universal set U. If n(p)=55% , n (q) = 50% and n(pUq)(compliment)=15%, find:

N(pUq)

Answer 1

Step-by-step explanation:

n(U) = 100%

n(p) = 55%

n(q) = 50%

n(pUq)' = 15%

n(U) - n (pUq)' = n(pUq)

=> (pUq) = 100% - 15%

= 85%

Hope it is correct :)

Answer 2

n(U) = 100%

n(p) = 55%

n(q) = 50%

n(pUq)' = 15%

n(U) - n (pUq)' = n(pUq)

=> (pUq) = 100% - 15%

= 85%
