Probability is a measure of the possibility of how likely an event will occur. It is a value between 0 and 1 which shows us how favorable is the occurrence of a condition. If the probability of an event is nearer to 0, let’s say 0.2 or 0.13 then the possibility of its occurrence is less. Whereas if the probability of an event is nearer to 1, lets say 0.92 or 0.88 then it is much favourable to occur. Show
Probability of an event The probability of an event can be defined as a number of favorable outcomes upon the total number of outcomes.
Some terms related to probability
When two dice are rolled what is the probability of getting same number on both?
Sample QuestionsQuestion 1: Find the probability of getting odd number on first dice and even number on other dice when two dice are thrown simultaneously. Answer:
Question 2: If two dice are thrown together then find the probability of getting 1 or 2 on either of the dice. Answer:
Question 3: In an event 2 dice are thrown simultaneously. Find the probability of getting prime number on first dice. Answer:
Question 4: Three coins are tossed together find the probability of getting at least one head and one tail. Answer:
Question 5: Find the probability of getting at least two tails when a coin is tossed three times. Answer:
When a dice is thrown one 5 find the probability of getting prime number?The probability of getting a prime number when a die is rolled is 1/2.
What is the probability of rolling five 3's with five fair dice?The answer is approximately 51.5%. If we sum the probabilities of the die showing 5's once and no times at all, then the remainder will give us the probability of a five appearing at least twice. To be clear, the probability of one 5 is not 0.03—it's approximately 0.3232.
What is probability of 3 when throwing dice once?Probability of getting 3 in a die = (number of favorable event) / (total number of event). P(3) = (1)/(6). Hence, the probability of getting 3 after tossing a rolling die is 1/6 or 0.167.
What is the probability of getting a prime number?Hence the probability of getting a prime number is 1/2.
