The probability of the friend completing the new level in her first try is 22.5%
<h3>What is probability?</h3>This is a concept that is used to talk about the likelihood or the chances of an event occuring.
For the digit 8, the frequency is 7
For the digit 9, the frequency is 11
The total number of frequencies is given as
10 + 9 + 6+ 7 + 8 + 12 + 4 + 6 + 7 + 11 = 80
7 + 11 = 18
Probability = 18/80
= 0.225 x 100
= 22.5%
