Answer:
B) 0.01
Step-by-step explanation:
If they want to know which one is very unlikely, you could turn them into percents.
1=100%
0.01=1%
0.9=90%
0=0%
0.6=60%
0.5=50%
0.35=35%
Since 0% is "impossible", not just "very unlikely", I'd go with 1%, which is B) 0.01
This is assuming I'm understanding your question correctly, since it doesn't actually ask a question.
