A survey was conducted in the class about their favorite subjects. 35% of the class voted for Math and Science. 45% of the class voted for Math. Find the percent of the class who voted for Math also voted for Science.

Answer 1

The percent of the class who voted for Math also voted for Science is 38.8%

How to find the percent who voted math and also voted for science?

Therefore,

1 = p(m) + p(s) - p(m ∩ s)

Hence,

p(m)  = 45% = 0.45

p(s)  = ?

p(m ∩ s) = 35% = 0.35

Therefore,

1 = 0.45 + p(s) - 0.35

1 - 0.45 + 0.35 = p(s)

p(s) = 0.9

Therefore,

p(m | s) = 0.35 / 0.9 = 0.38888888888 = 38.8%
