The expected number of left-handed people in the sample= 45

<h3>Calculation of total number of left-handed</h3>

The number of people selected at random= 450

The percentage of people that are left-handed =10%

Therefore, the number of people that are left-handed,

= 10/100 * 450

= 4500/100

= 45
