Calculating Probability for Two Events: Longer Than 24.5 Minutes

In summary, the formula for calculating the probability of two events longer than 24.5 minutes is P(A and B) = P(A) * P(B). To calculate this probability, you will need to know the individual probabilities of each event and whether they are independent or dependent. If the events are independent, you can simply multiply the probabilities, but if they are dependent, you will need to use conditional probability. The difference between calculating the probability for independent and dependent events is that for dependent events, the occurrence of one event affects the probability of the other. The probability for two events longer than 24.5 minutes can be interpreted as the likelihood of both events occurring within a given time frame or the chance of both events happening at the

As the question says the probability that both of them were longer than 24.5 minutes i'd of thought it would be in the 24-29 row, so that means 8/55 * 7/54, but the answer is 11/55 * 10/54, where did they get 11 from?

How many ways are to choose 2 from the over 24.5 minute group? How many ways are there to choose 2 overall?

oh god I am stupid, thank you.
 

FAQ: Calculating Probability for Two Events: Longer Than 24.5 Minutes

What is the formula for calculating the probability for two events longer than 24.5 minutes?

The formula for calculating the probability of two events longer than 24.5 minutes is P(A and B) = P(A) * P(B).

What information is needed to calculate the probability for two events longer than 24.5 minutes?

To calculate the probability for two events longer than 24.5 minutes, you will need to know the individual probabilities of each event and whether the events are independent or dependent.

How do you determine if the events are independent or dependent when calculating the probability for two events longer than 24.5 minutes?

If the occurrence of one event does not affect the probability of the other event, then the events are considered independent. If the occurrence of one event does affect the probability of the other event, then the events are considered dependent.

What is the difference between calculating the probability for independent events and dependent events?

When calculating the probability for independent events, you can simply multiply the individual probabilities. However, when calculating the probability for dependent events, you will need to use conditional probability and take into account the effect of one event on the other.

How can the probability for two events longer than 24.5 minutes be interpreted?

The probability for two events longer than 24.5 minutes can be interpreted as the likelihood that both events will occur within a given time frame. It can also be interpreted as the chance that both events will happen at the same time.
