It shows possible values and their probabilities.
0, 1, 2, or 3 heads.
P(X = 1) = 0.375 or 37.5% (correct calculation).
It has two outcomes: success and failure.
p + q = 1.
P = p^2 = (0.3)^2 = 0.09.
P(X = 1) = n * p * (1-p)^(n-1) for n trials.
Multiply probabilities: P = (5/8) * (5/8) = 25/64.
Use favorable outcomes over total possible outcomes.
Use P(no 6) = (1 - P(6))^n for n rolls.
