Weighted probability

A company Txs Tools, a company selling hardware tools, is looking to expand out of their home market A into Market B. They have done some market research, and have received the following numeric probabilities:

Sales Level (USD)	Probability (%)
0	5
200	10
300	40
500	20
800	25

Txs Tools will only be motivated to expand if they can have reasonable assurance that they will achieve sales of 400 or more based on a weighted probability.

Calculate the weighted probability for the sales level of Txs tools based on the probability table, by creating a combined sales_probability list with pair values as a string separated by a pipe character |.
Multiply the values in each list by converting the values back to float, add the totals together, and call the result weighted_probability.
Print the weighted_probability result.
