Question

hi guys......... help me out

A survey shows that 63% Anericans like cheese, whereas 76% likes apple, if x% of Americans likes both cheese and apple, then find the value of x?​

Answer 1

Answer:

39%

Step-by-step explanation:

since survey result is in percentage, we take total as 100 %

let n(s) be percentage of Americans who like cheese

given n(c) = 63

further, n(a) is percentage of Americans who like aapke

n(a) = 76

n(x) percentage of Americans who like both I.e. n(c intersection a)

now using set theorem

n(c union a) = n(c) + n(a) - n(c intersection a)

100 = 63+76-x

x = 139-100

x= 39%
