C. 40
Step-by-step explanation:
There are <em>3</em> <em>sectors</em> that are labeled five, which is <em>out of 12</em>. So the <em>chance of landing on one of it is 3/12, or 1/4</em>.
So, a reasonable estimate is that <em>out of 150 spins, 1/4 of them will land on five</em>. The number of spins can be found out by <em>multiplying 150 by 1/4</em>. 150 * 1/4 is equal to <em>37.5</em>, which is about 40.
