A coin is flipped 50 times, and heads appear 30 times. Let the random variable X represent the outcome of flipping heads. What is the experimental probability distribution for X?
P(X = heads) = 0.5, P(X = tails) = 0.5
P(X = heads) = 0.3, P(X = tails) = 0.7
P(X = heads) = 0.6, P(X = tails) = 0.4
P(X = heads) = 0.7, P(X = tails) = 0.3

A spinner with 4 equal sections (red, blue, green, yellow) is spun 20 times. It lands on red 6 times, blue 5 times, green 4 times, and yellow 5 times. What is the experimental probability distribution for the spinner?
P(red) = 0.4, P(blue) = 0.3, P(green) = 0.2, P(yellow) = 0.1
P(red) = 0.3, P(blue) = 0.25, P(green) = 0.2, P(yellow) = 0.25
P(red) = 0.5, P(blue) = 0.25, P(green) = 0.15, P(yellow) = 0.1
P(red) = 0.6, P(blue) = 0.15, P(green) = 0.1, P(yellow) = 0.15

A dice is rolled 30 times. The results show the following frequencies: 1 appears 5 times, 2 appears 7 times, 3 appears 4 times, 4 appears 6 times, 5 appears 3 times, and 6 appears 5 times. What is the experimental probability distribution for the outcomes?
P(1) = 0.2, P(2) = 0.3, P(3) = 0.1, P(4) = 0.2, P(5) = 0.1, P(6) = 0.1
P(1) = 0.15, P(2) = 0.25, P(3) = 0.1, P(4) = 0.2, P(5) = 0.1, P(6) = 0.2
P(1) = 0.1, P(2) = 0.233, P(3) = 0.133, P(4) = 0.2, P(5) = 0.1, P(6) = 0.133
P(1) = 0.167, P(2) = 0.233, P(3) = 0.133, P(4) = 0.2, P(5) = 0.1, P(6) = 0.167
