Prob (Both are type O)=(.45)(.35)= .1575 Prob (both are the same type) =P (both are type O or both are type A or both are type B or both are type AB ) =P(both are type O)+ P(both are type A)+ P(both are type B)+ P(both are type AB)= (.45)(.35)+ (.40)(.27)+ (.11)(.26)+ (.04)(.12)= .2989 4.16 (10 points, 5 points for the first answer, and 5 points for the second answer) Ans.
