What is the probability that if you multiply two randomly-selected two-digit whole numbers, the result is greater than 100 and less than 200

4/675

Step-by-step explanation:

There can be 90  two-digit numbers ranging from 10 to 99. There will be

90 x 90= 8100 possibilities of randomly selecting and combining 2 entire two-digit numbers, if we find ax b to be distinct from bx a. When 10 is first chosen, there may be 9 two-digit numbers that could be combined within the required range for a product When 11 is chosen first, then the second two-digit number has 9 possibilities. 12 has seven options; 13 has six options; 14 has five options; 15 has four options; 16 has three options; 17 has two options; 18 has 2 options; and 19 has one option. It provides us 48 total choices so the likelihood that the combination of two randomly chosen two-digit whole numbers is one of theses  these possibilities is thus 48/8100 = 4/675.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
