In this video, I will go over methods for finding the mean and standard deviation of a binomial distribution. It is important to completely understand what is expected of you when asked to Apply probability distributions in solving problems.

ACHIEVED: Apply probability distributions in solving problems involves:
• selecting and using methods
• demonstrating knowledge of concepts and terms
• communicating using appropriate representations.

MERIT: Relational thinking involves one or more of:
• selecting and carrying out a logical sequence of steps
• connecting different concepts or representations
• demonstrating understanding of concepts;
and also relating findings to a context or communicating thinking using appropriate statements.

EXCELLENCE: Extended abstract thinking involves one or more of:
• devising a strategy to investigate or solve a problem
• identifying relevant concepts in context
• developing a chain of logical reasoning
• making a generalisation;
and also, where appropriate, using contextual knowledge to reflect on the answer.

Problems are situations that provide opportunities to apply knowledge or understanding of mathematical and statistical concepts and methods. Situations will be set in real-life or statistical contexts.

Methods are selected from those related to:
• discrete and continuous probability distributions
• mean and standard deviation of random variables
• distribution of true probabilities versus distribution of model estimates of probabilities versus distribution of experimental estimates of probabilities.
