Since we are given the values for both rows only in the second column, we can use this to solve for the rest of the missing values. Simply divide 3 by 2.49 and multiply that resultant by and multiply that by any missing value for cookies to find the missing cost. In order to solve for the cookies when cost is given, divide 2.49 by 3 and multiply that resultant. I will solve for the first, third, and fourth columns.

3/29=1.2
For column 1, 1.2*1=1.20
For column 3, 1.2*20=24.10
For column 4, 1.2*100=12.00

The probability is 0.1587.

The z-score associated with this is found using the formula

z = (X-μ)/σ = (100-90)/10 = 10/10 = 1.0

Using a z-table (http://www.z-table.com) we see that the area to the left of, less than, this is 0.8413.  We want the area greater than, so we subtract from 1:
1 - 0.8413 = 0.1587
