In mathematics, binomial coefficients are represented as \(\binom{a}{b}\), where \(a\) is the \((a-1)^{\text{th}}\) row, and \(b\) is the \((b-1)^{\text{th}}\) number in that row, counting from the left, acting as an index.
Hockey is a team sport that incorporates balance, endurance, and hand-eye coordination. Choosing the proper hockey equipment is important to protect from injuries or dental damage. Hockey players need to drink plenty of water because the heat and weight of the equipment can cause dehydration.
Penalty (ice hockey) A penalty in ice hockey is a punishment for an infringement of the rules. Most penalties are enforced by detaining the offending player within a penalty box for a set number of minutes, during which the player may not participate in play. Penalties are called and enforced by the referee, or in some cases the linesmen.
