Question 916697
There are a total of 18+17+5 = 40 people


5 of them are redheads


-------------------------------------------------------


P(redhead) = (# of redheads)/(# of people total)


P(redhead) = 5/40


P(redhead) = <font size=5 color="red">1/8</font> (don't forget to reduce fully)



The probability of selecting a redhead is <font size=5 color="red">1/8</font>
