So in this case, the favorable outcomes would be the female musicians. So we're looking to find a number of female musicians, and on the bottom would be all outcomes, which would be all musicians.

We can go to the bottom of that same column or the find the total on the far left and follow that all the way to the right. Either way, you'll see that there's 100 and 30 musicians total, which gives us when me divide it, a probability of zero 0.554 for the probability that a musician
