Can you just explain me how u did that?
The formula of average is > The sum of the moments happend / the number of the events, here the sum is 10 + 6 and it is 2 times, hence its 8
In other words it is the sum divided by the count.
Thanks
add up all the numbers, then divide by how many numbers there are
Welcome :)
