Y = 8x + 29 is the answer for your question
You just have to divide the decimals
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%
5 + 3{96 + 20 + 4}
5 + 3{116 + 4}
5 + 3{120}
5 + 360
365
