yes
sohailiftikhar

it can be read as P of E such that of F

oops those P's should be A's lol

now that you know what \(P(A|B)\) means, see if you can solve below problem |dw:1439733513721:dw|

A person is picked from the village at random. Find the probability that the person is a man, given that the person is 70 years or older
mathmath333
  • mathmath333
i just started learning it . can't solve
ganeshie8
  • ganeshie8
sure you can, you don't really need to know that formula you will discover that formula while solving the above problem
ganeshie8
  • ganeshie8
you're given that the person is 70 or older, so "only look at that column" : |dw:1439734227337:dw|
ganeshie8
  • ganeshie8
how many are 70 or older ? how many of them are men ?
mathmath333
  • mathmath333
5
mathmath333
  • mathmath333
70 old > 50 persons
ganeshie8
  • ganeshie8
there are 25 people that are 70 or older right ?
mathmath333
  • mathmath333
yes 25
