Question 1205431
<font color=black size=3>
Answer: <font color=red>40%</font>


Reason: 
Let's say there are 100 people surveyed.
50 have brown hair (since 50% of 100 is 50).
25 have blonde hair
15 have black hair
10 have red hair
Then 25+15 = 40 people have either blonde or black hair out of the 100 total. That's a 40/100 = <font color=red>40%</font> chance.
The percentage 40% converts to the exact decimal form 0.40 or simply 0.4
If you want to convert to a fraction, then 0.4 = 2/5
