A researcher surveyed people as they left a museum, asking whether they visited the gift shop and whether they watched the film
BARSIC [14]
Hey there!


P(y) = 0.46

P(x) = 0.49

P(y') = 0.54

P(x') = 0.51

P(y and x') = 0

x = person that watched the film

y = person that visited the gift shop


 P(y and x') / P(x')

0.1 / 0.51 = 0.196 

Now convert that into a percentage!

0.196 = 19.6%

Your answer is 19.6%
