Answer:
65%
Explanation:
Molar mass of chlorine: 71
Molar mass of ethane: 30
R1 / R2 = root M2 / M1
= root 30 / 71
= 0.65

Answer: 0.85 (Choice A)</h3>
===========================================================
Explanation:
x = number of siblings
We add the probability values that correspond to x = 0 and x = 1, which is when the person has 0 siblings and 1 sibling respectively.
Those probabilities are: 0.20 and 0.65
So we get 0.20+0.65 = 0.85
There's an 85% chance of randomly picking someone who has fewer than two siblings.
