Developing Empirical Probability Distributions, Expected Value Practice Test

A spinner game is played 120 times. The observed counts are: land on 1 (18 times), land on 2 (27 times), land on 3 (33 times), land on 4 (42 times). Define the random variable $X$ as the number landed on. Using relative frequencies from these data as estimated probabilities, what is the expected value of $X$ based on the empirical distribution?

A delivery app sampled 100 orders and recorded the tip amount (in dollars). Observed counts: $X=0$ (12 orders), $X=2$ (34 orders), $X=4$ (41 orders), $X=7$ (13 orders). Using the relative frequencies from this sample as estimated probabilities, what is the expected value of $X$ based on the empirical distribution?
