A miniature golf course recently provided a number of customers with golf b***s, including 7 white golf b***s and 7 other golf b***s. Based

based on the observation so far the probabilty of getting a white ball is

$${\frac{{\mathtt{7}}}{{\mathtt{14}}}} = {\mathtt{0.5}}$$

so you'd expect that of then next 18 b***s

$${\mathtt{18}}{\mathtt{\,\times\,}}{\mathtt{0.5}} = {\mathtt{9}}$$

b***s would be white

I don't think that I understand the question!
