Answer:
0.0256 or 16/625 or 2.56%
Step-by-step explanation:
The problem states that each light bulb operates independently of the other, so the probability doesn't change for each light bulb based on how many other light bulbs are working.
The probability of each light bulb working is 0.6 out of 1. However, we want the probability of it being broken.
1 - 0.6 = 0.4
This is the probability of one light bulb being broken. But there are 4 lightbulbs.
We can multiply 0.4 by itself 4 times, as the probability stacks.
0.4 * 0.4 * 0.4 * 0.4 = 0.0256 (<em>Also achieved by raising 0.4 to the power of 4)</em>
<em>To get the percentage, multiply it by 100. 2.56%</em>
<em />
0.4 is equal to 40% or 40/100. If you simply, that fraction is equal to 2/5
2/5 * 2/5 * 2/5 * 2/5 = 16/625 (<em>Also achieved by raising 2/5 to the power of 4)</em>
The answer is 20 millimeters because there is 100 millimeters and to make 10 masks 20 millimeters times 5 is 1 meters and 5 masks

Tough question .. math ?? If it is I gotta think about that question there
Zero is actually a whole number, rational number, and integer, but it is not a natural number
