This is another way of saying "there is a 50/50 chance"
What is an even chance?
100
This is the probability that a number larger than four will result when a die/dice is thrown.
What is 1/3?
100
This describes an event with a probability that is between 0.5 and 1.
What is 'likely'?
100
What is the sum of the probabilities of all possible outcomes of any event? (The answer is a number.)
What is 1 or 100%?
100
This is the probability of a heads coming up on a fair coin toss.
What is 1/2, 0.5, 50%.
200
This is the number of cards of each suit in a standard pack of cards.
What is thirteen?
200
This is the probability that a zero will be thrown on a standard die/dice.
What is zero?
200
This describes an event with a probability of zero.
What is 'impossible'?
200
What is the complementary event to "we will win the game?"
What is "we will not win the game"?
200
This is the probability of not tossing a heads on a fair coin toss.
What is 0.5, 50% or 1/2?
300
This is what 'all the possible outcomes' of an event is called.
What is the sample space?
300
This is the probability that a four will be thrown on a die/dice if the last three throws were all fours.
What is 1/6?
300
This is what is meant by 'certain'.
What is having a probability of one or 100%?
300
If the probability of it raining tomorrow is 30%, this is the probability of it not raining tomorrow.
What is 70%, 0.7 or 7/10?
300
This is the probability of tossing two heads in a row using a fair coin toss.
What is 1/4, 0.25, or 25%?
400
This is what 'an event where each possible outcome is equally likely' is called.
What is a simple event?
400
This is the probability that a number less than six will be thrown on a stand die/dice.
What is 5/6?
400
This is how the probability of an event happening is found if all outcomes are equally likely.
What is dividing the number of favourable outcomes by the total number of outcomes?
400
This is the probability that a red card (either a heart or a diamond) will be drawn randomly from a standard pack of playing cards.
What 50%, 1/2, or 0.5?
400
This is the probability of not tossing two heads in a row using a fair coin toss.
What is 75%, 0.75 or 3/4?
500
This is what 'all possible outcomes outside an event' are called.
What are complementary events?
500
This is the probability that a three was thrown on a die/dice, if we know a one was not thrown.
What is 4/5?
500
This is the probability of drawing a randomly drawing a blue counter from a jar that contains 999 white counters and one blue one?
What is 999/1000 or 99.9%?
500
This is the number of colours of tickets in a raffle if the probability of drawing each of a red, green, and blue ticket is as follows: P(red)=0.35, P(green)=0.35, and P(blue)=0.30
What is three?
500
This is the probability of not tossing three heads in a row using a fair coin toss.
