GED Math Problem of the Day #15 - How to Calculate Probabilities

#GED #GEDMath #GED Test

In this GED math problem of the day, I show you how to calculate probabilities!

Note: Just to clarify what I was saying at 11:41 more, you can't (usually) compare two fractions just by looking at the numerators (top numbers). You can only do this (reliably) when the denominators (bottom numbers) are the same. For example, say we simplify 36/100 to 18/50 and compare 18/50 to 35/100. 18 is a smaller number than 35. However, 18/50 is still a bigger number than 35/100. That's what I meant when I said that even when these two fractions are written in simplified forms and compared, 36/100 is always a bigger number than 35/100. You just have to get a common denominator and then this will be obvious.

You made a mistake at 4:54 this is a dependent event meaning after he draws the blue marble there are now 99 marbles left in total so P(G) =15/99

This is not even math deserving, just by seeing that red marbles has the highest number, this one is just have a higher chance
