**A shot** is a single execution of a quantum algorithm on a QPU. A “shot” is a single execution of a quantum algorithm on a QPU. For example, a shot is a single pass through each stage of a complete quantum circuit on a gate-based QPU. **Shots** are implementations of identical experiments that have same _algorithm_ and same _parameters (initial states)_. However, we can repeat **experiments** with different _parameters_ while we keep number of shots the same for each experiment. **Per Shot Price depends** on the type of QPU and not on the no. or type of gates used in the quantum circuit or the no. of variables in a quantum annealing problem. **A task** is a sequence of repeated shots based on the same circuit design or annealing problem. In Amazon Braket, you define the no. of shots you want included in a task when you submit it. Quantum Algorithms are probabilistic, not deterministic. So there is no single correct result from a quantum operation. Rather the outputs are aggregated and averaged to determine the correct output. For this reason, algorithms are run many many times (10,000 times is a standard number)
