Answer:
2%, low probability
Explanation:
In this case we have that the avatars are distributed as follows:
5 subjects and 10 versions of the application for each subject, therefore they are a total of:
5 * 10 = 50
In total there are 50 avatars.
To know the probability that I get 1 in specific, in this case that of a lion is:
1/50 = 0.02
The probability is 2%, that is to say a really low probability, that is to say that the most probable thing is that you do not receive it.
