Experiment 1: A spinner has 4 same sectors colored yellow, blue, green, and also red. What is the probability of landing on violet after turn the spinner?



Probability: It is difficult to floor on purple due to the fact that the crackhead does no contain this color.

You are watching: What is the probability of a certain event

P(purple) = 0 = 0

Experiment 2: A teacher chooses a student at arbitrarily from a class of 30 girls. What is the probability the the student liked is a girl?

Probability: Since every the student in the class are girls, the teacher is particular to choose a girl.

P(girl) = 30 = 1

In the an initial experiment, it was not possible to land on purple. This is an instance of an impossible event. In the 2nd experiment, selecting a girl was specific to occur. This is an instance of a certain event.

The next experiment will involve a traditional deck of 52 playing cards, which consists of 4 suits: hearts, clubs, diamonds and also spades. Each suit has actually 13 cards together follows: ace, deuce, three, four, five, six, seven, eight, nine, ten, jack, queen, and king. Picture cards encompass jacks, queens and kings. There are no joker cards. There are just 4 of a kind, because that example, 4 tens.

Experiment 3: A solitary card is favored at random from a traditional deck that 52 play cards. What is the probability the the card liked is a joker card?

Probability: It is difficult to pick a joker card because a conventional deck the cards does not contain any kind of jokers. This is an difficult event.

P(joker) =  0  = 0

Experiment 4: A single 6-sided dice is rolled. What is the probability of roll a number less than 7?

Probability: Rolling a number less than 7 is a certain event due to the fact that a single die has actually 6 sides, numbered 1 with 6.

P(number 6 = 1



Experiment 5: A total of 5 cards are liked at arbitrarily from a standard deck that 52 play cards. What is the probability of picking 5 aces?

Probability: It is impossible to select 5 aces due to the fact that a typical deck that cards has actually only 4 that a kind. This is an difficult event.

P(5 aces) =  0  = 0

Experiment 6: A glass jar consists of 15 red marbles. If a single marble is favored at random from the jar, what is the probability the it is red?

Probability: Choosing a red marble is specific to occur since all 15 marbles in the jar space red. This is a particular event.

P(red) = 15 = 1

Summary: The probability of an occasion is the measure of the opportunity that the event will happen as a result of the experiment. The probability of an occasion A, symbolized through P(A), is a number between 0 and also 1, inclusive, that measures the likelihood of an event in the following way:

If P(A) > P(B) then event A is much more likely to occur than event B.If P(A) = P(B) then events A and B are equally likely to occur.If occasion A is impossible, climate P(A) = 0.If event A is certain, climate P(A) = 1.

3. What is the probability of selecting 14 hearts from a conventional deck of 52 playing cards?




None of the above.


4. If a number is chosen at random from the following list, then what is the probability the it is prime?

2, 3, 5, 7, 11, 13, 17, 19
