IB DP Maths: AA SL复习笔记4.5.2 Calculating Binomial Probabilities
Calculating Binomial Probabilities
How do I calculate?P(X?=?x):?the probability of a single value for a binomial distribution?
How do I calculate P(a?≤?X?≤?b):?the cumulative probabilities for a binomial distribution??
How do I find probabilities if my GDC only calculates P(X?≤?x)?
What if an inequality does not have the equals sign (strict inequality)??
Exam Tip
- If the question is in context then write down the inequality as well as the final answer
- This means you still might gain a mark even if you accidentally type the wrong numbers into your GDC
