So far

So far on its tour, a band sold out 3 shows and did not sell out the other 3 shows. Considering this data, how many of the band's next 4 shows would you expect to be sold out?

Final Answer:

x =  2

Step-by-step explanation:

$$\begin{gathered} p=\frac{3}{3+3}=\frac{1}{2}=0.5 \\ x=4\cdot p=4\cdot \frac{1}{2}=\frac{4\cdot 1}{2}=\frac{4}{2}=2 \end{gathered}$$
