"Math is Stupid"

• sirfwalgman: math is stupid
• sirfwalgman: "I have two children, one is a boy who prefers the colour Red. What is the probability I have two boys".
  
  
  As we know, without the modifier, the probability is 1/3*
  
  BB
  BG
  GB
• sirfwalgman: it's 50/50 that your other kid is a boy period right?
• sirfwalgman: and whats the difference between BG and GB
• Me: it is 5050 that you have 1 boy if 1 child
• Me: it is also 50/50 2nd child is boy
• Me: it is the classic Let's Make a deal Monty Hall problem
• sirfwalgman: not according to moronic statistics people
• Me: dude
• sirfwalgman: I am currently idle.
• sirfwalgman: ya
• Me: you fail to understanbd either problem
• sirfwalgman: aparently
• Me: if you have 2 children it is 25 % you will have 2 girls, 25% you will have 2 boys
• Me: and 50% you have one of each
• Me: do we agree?
• sirfwalgman: i said that
• Me: If child is already born than you have case where questioner intentionally picked boy
• Me: so there are 3 cases available
• Me: and 2 of the cases other child is girl
• Me: but probability of future child being boy is 50/50
• Me: because questioner has no control

• I spend a little too much of my time each day trying to explain probabilities to waffles.

Probability from work yesterday:

Project manager came back from his vacation yesterday.

Odds of him applying pressure on slowest part of project when he returned is obviously 100%

(Similar odds of me missing VeryJosie and Mookie also 100%)

One of task was to help newest member of project team get the 10 people who have to approve a board being ready for build to sign off.

I was assigned 4 names randomly, 2 other people got 3 names.

Half of the 10 people had already approved.

What were the odds my 4 randomly assigned people had already approved?

Waffles don't even waste your time answering.
