A Bin at the Store Is Filled with T-Shirts $0.5$ You Need to Buy Four T-Shirts for Your Friends

A bin at the store is filled with T-shirts. They are all sized either small or large, and there are approximately equal numbers of each, so the chance of picking either size is $0.5$ . You need to buy four T-shirts for your friends, three larges and one small. You want to know how many shirts you must pull out of the bin before you have at least three larges and one small. Use the random numbers table below to simulate your $\mathrm { T }$ -shirt selections. The highlighted numbers were randomly chosen and serve as the first selections for the different trials. Repeat the simulation five times, beginning each trial at a different highlighted number. Work down the columns, and move from left to right, column to column as needed.

Let the even digits correspond to selecting a small, and the odd digits correspond to select a large.
$\begin{array}{l|l}\text { Number } & \text { Size } \\\hline 0,2,4,6,8 & \text { Small } \\1,3,5,7,9 & \text { Large }\end{array}$

What is the greatest number of shirts your experiments indicate you need to pull out of thı before you have three larges and one small?
