Part of video series Probability
Taught by MrBurnett
An introduction to some terms in probability and how to determine the probability of several different events.
  • What is a probability scale?
  • What is the formula for determining the probability of an event?
  • What values are possible for the probability of an event?
  • What is an expected frequency of an event happening?
  • What is the difference between expected and observed frequency or probability?
  • If there are 5 red balls, 2 blue balls, and 3 green balls in a bag, what is the probability of drawing a red ball or p(red)?
  • If there are 5 red balls, 2 blue balls, and 3 green balls in a bag, what is the probability of NOT drawing a green ball or p(not green)?
  • If there are 5 red balls, 2 blue balls, and 3 green balls in a bag, what is the probability of drawing a yellow ball or p(yellow)?
  • If there are 5 red balls, 2 blue balls, and 3 green balls in a bag, you pick a green ball and do not replace it in the bag, what is the probability of drawing another green ball or p(green given green)?
  • If there are 5 red balls, 2 blue balls, and 3 green balls in a bag, you pick a green ball and do not replace it in the bag, what is the probability of drawing a red ball or p(red given green)?
  • Why does p(not e) = 1 - P(e)?
  • What are mutually exclusive events?
  • When does P(a or b) = P(a) + P(b)?
  • What is the probability of rolling a 4 or 6 on a die or P(4 or 6)?
  • What are possibility space diagrams?
  • If you roll two dice, one red, one blue, and you add the scores to find your total score, why are there 36 equally likely outcomes and what are they?
  • What is the probability of rolling a 7 when you roll two dice?
  • What is the probability or getting a score greater than 8 when you roll 2 dice?
  • What is the probability of rolling a prime number score when you roll 2 dice?
  • What are independent events in probability?
  • When you toss a coin and roll a die, what is the probability of flipping a head and rolling a 5 or p(head and 5)?
This is a basic introduction to probability and how to calculate some various probability of events. You will get a crash course in some important probability concepts and formulas as well. This is a very good lesson for learning some quick probability concepts.
