Answer:
<h3>Step 4</h3>
Step-by-step explanation:
Given the expression 7+(-2)
Let 7 be 7 positive tiles since it is a positive number
Let -2 be 2 negative tiles being a negative number
7+(-2) = 7 positive tiles <em>and</em> 2 negative tiles
note that + * - will give minus sigh (-), the expression will become:
7+(-2) = 7-2
7-2 = 5
Hence the expression gives 5 positive tiles not 2 positive tiles according to Jillian calculations in step 4.
Hence Jillian made an error in step 4
Answer
probability of greater than 3 is 60%
not 5,6,7 or 8 is 60%
2.125*10^4 x 10^4 / 1.25 x 10^3
= (2.125 / 1.25) x 10^(4 - 3)
= 1.7 x 10^1
= 17
Answer
17 times greater
