Maths probability question

Answer 1

You have to figure out how many of the 46 play cards and/or baseball.

27 play cards (that willl be the blue plus the orange)
18 play baseball only (that is the green)
(we can figure the number in the orange(both) must be 9, because 27 play baseball, but 18 play only baseball)

27+18= 45

so that means 45 out of 46 people play one or both. the probability of picking the one person who plays neither is 1/46

You have to change that to a decimal, rounded to 2 places.
