Timothy Klein · Answer 1

2%, low probability

Step-by-step 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.
