Step-by-step explanation
the probability of an event is the ratio of the favorable outcomes to the total outcomes

then
from the given data
Let

so
Step 1
Write this probability as a percent:
a) percent
to do that, multiply by 100%
so

so
a) 85%
b)fraction:
to do that, multiply numerator and denominator by 100 and simplify
so

therefore
b)

so, the probability of choosing one orange elastic band si 17/20,
Step 2
to fiind the best word to describe the probability we need to check in the likelihood scale

so, the answer is
Likely
I hope this helps you
