What is - 4/5 times -5/7?
20/35 or in simplified form 4/7

The answer is 4/7

4 5
- * -
5 7
Multiply across so 4*5 is 20 and 5*7 is 35
You can simplify that by 5 so the answer would be positive 4/7.
Remember a negative times a negative is positive and a positive times a positive is a positive.
Different signs like negative times a positive would result in a negative answer.

deff fn [24]
When calculating probability you need to remember that probability is:
something that you are observing divided by total number of participants.
The number you get is relative value(has value between 0 and 1) and if you want to get it in percentage (more clearly) just multiply it with 100.

In this case we are observing blood type B persons. Number of them is 165.
Total number of persons is 1500. Therefore our calculation looks like this:

165/1500 = 0.11    or  the probability is 0.11*100=11%
