Based on the calculation below, the likelihood that if someone died they were a heavy smoker is 42.11%.
<h3>How do we calculate the likelihood of an occurrence?</h3>
Let:
Likelihood that a non-smoker will die = x
Therefore, we have:
Likelihood that a light smoker will die = 2 * x = 2x
Likelihood that a heavy smoker will die= 2 * 2x = 4x
From the above, we have:
Expected number of non smokers that will die = 50% * x = 0.5x
Expected number of light smokers that will die = 30% * 2x = 60%x = 0.6x
Expected number of heavy smokers that will die = 20% * 4x = 80%x = 0.8x
Total expected = 0.5x + 0.6x + 0.8x = 1.9x
Therefore, we have:
Likelihood that a heavy smoker died = Expected number of heavy smokers that will die / Total expected = 0.8x / 1.9x = 0.4211, or 42.11%

Answer: x=-3
Step-by-step explanation:
2x-4(x+3)=x-3
2x-4x-12=x-3
-2x-12=x-3. add 12 to both sides
-2x=x+9. subtract x from both sides
-3x=9. Divide both sides by -3
x=-3
Answer: The answer is: 3x^{3} -5x^{2} +10x -10 + {7}{x + 1}
X • 1 + x/1
x + x/1
2x/1
=2x
