Hi Monica! So let's think this through.
If we expect to get a heart 6 times in 180 trials, then "theoretically" we will see 6 hearts in 180 trials.
But the question, I think, is asking what the probability of getting a heart is in 1 trial, not 180. The answer, it turns out, is also 6/180, which can also be written as 1/30 or 0.033.
Thinking of it backwards may help. Say the probability of a heart on any given trial is 0.033333. Then over 180 trials, we would expect to see 0.033333*180 = 6 hearts!
Hope that helps!
