Lets break this down step by step.
4+4+4+4=16 lawns a week.
16+16+16+16=64 lawns a month.
64+64+64+64=256 lawns a year.
Then we take 256 x $25 to get $6,400 last year.

Using it's concept, the probability of choosing a number that is a multiple of 9 is of 0.111.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
From 1 to 81, there are 81 numbers, of which 81/9 = 9 are multiples of 9, hence, considering that 81 is the number of total outcomes and that 9 is the number of desired outcomes, the probability is given the following division:
p = 9/81 = 1/9 = 0.111.
