It's a Sunday evening and Hoodie Sharif needs to decide what hoodie he needs to wear for Monday. Hoodie Sharif has 30 hoodies. He has 15 black hoodies 12 gray hoodies and 3 red hoodies. What is the probablitly that Hoodie Sharif will select a black hoodie?
What do I do? I need to make a selection for a hoodie for tomorrow.
So if I want to select a black hoodie I'm going to have to see what my odds are.
I've got it! I was able to select a black hoodie! I had a 15/30 chance more so a 50% chance of selecting one! I added both the red and gray hoodies then subtracted them by 15 and got a 50% chance.
I have a 12/30 chance of pulling out a gray hoodie.
