One equation with a decimal: 2.5x + 5 = 10
One real world problem that is solved by an equation: At the beginning, I had 5 cups of flour. I made a batch of cookies. Now, I have 3.5 cups of flour. How much flour did I use? 5 - x = 3.5
Hope this helps!! :) If there's anything else that I can help you with, please let me know!
<h3>Sample space = {a,b,c,d,e,f}</h3><h3>Event space = {a,c}</h3>
We simply list all of the letters mentioned as they are the possible outcomes. We can only pick one item from the sample space. The event space is the set of outcomes where we want to happen (picking either an 'a' or 'c').
