  • Explanation → Probability
    EvidenceWork through a complete Khan Academy dice problem: on a fair six-sided die, the even faces 2, 4 and 6 give a single-roll probability of 3/6=1/2. Assuming three mutually independent rolls, multiply three one-half factors to obtain 1/8 for an even result on every roll. Editorial notes distinguish fairness from independence and clarify that pairwise independence alone does not justify a three-event product.
  • Content location → Independence
    EvidenceFor two events, independence means one event does not change the other event probability. Repeated rolls in this example are assumed independent; a fair die alone does not imply this.
