Answer 1

`\begin{gathered} \text{the type }B\text{ donations are all that are not type O, or A or AB, so it is } \\ 1-(7)/(16)-(3)/(8)-(1)/(16)=(16)/(16)-(7)/(16)-(6)/(16)-(1)/(16) \\ =(16-7-6-1)/(16) \\ =(2)/(16) \\ =(1)/(8) \\ \\ So\text{ 1/8 part of the blood donations are Type B} \end{gathered}`
