To calculate the probability of an independent compound event using "and" or "then", you would use the operation of multiplication (*).
For example, if the probability of event A occurring is 0.5 and the probability of event B occurring is 0.6, the probability of both events A and B occurring would be 0.5 * 0.6 = 0.3.
To calculate the probability of a dependent compound event using "and" or "then", you would also use the operation of multiplication (*), but the probabilities would be adjusted based on the outcome of the first event.
For example, if the probability of event A occurring is 0.5 and the probability of event B occurring given that event A has already occurred is 0.4, the probability of both events A and B occurring would be 0.5 * 0.4 = 0.2.
To calculate the probability of a compound event using "or", you would use the operation of addition (+).
For example, if the probability of event A occurring is 0.3 and the probability of event B occurring is 0.4, the probability of either event A or event B occurring would be 0.3 + 0.4 = 0.7.
Which operation would you use to calculate each
+ (add) - (subtract) * (multiply) ÷ (divide)
