Answer 1

Answer:

The probability that the next person to visit the store will buy 2 or more items is;

$\frac{1}{3}$

Explanation:

Given that;

48 people bought 1 item

32 people bought 2 or more items

16 people did not buy anything items

Total number of samples;

$N=48+32+16=96$

The probability that the next person to visit the store will buy 2 or more items is;

$\begin{gathered} P_2=\frac{N_2}{N}=\frac{32}{96} \\ P_2=\frac{1}{3} \end{gathered}$

Therefore, the probability that the next person to visit the store will buy 2 or more items is;

$\frac{1}{3}$
