When a die is thrown what is the probability of getting a number less than 5?
β΄ The probability of getting a number less than 5= 46= 23.
When an unbiased dice is tossed once what is the probability of getting an even number?
In a single throw of an unbiased dice, you can get any one of the outcomes: 1, 2, 3, 4, 5, or 6. So, exhaustive number of cases = 6. (i) An even number is obtained if you obtain any one of 2, 4, 6 as an outcome. So, favourable number of cases = 3.
What is the probability of getting a number less than 2 on a dice?
Probability of rolling less than certain number with one die
| Roll less than a⦠| Probability |
|---|---|
| 1 | 0/6 (0\%) |
| 2 | 1/6 (16.667\%) |
| 3 | 2/6 (33.33\%) |
| 4 | 3/6 (50\%) |
When an unbiased dice is thrown?
That is when a dice is rolled the faces that can be shown are 1,2,3,4,5,6 here by saying that the dice is unbiased means that the probability of showing any one of the 1,2,3,4,5,6 numbers is equal.
When an unbiased dice is thrown once?
What is the probability of getting a number less than 4?
Answer: The probability of getting a number less than 4 is 3/6.
How many times is an unbiased die thrown?
An unbiased die is thrown once. What is the probability of getting a number less than 5? When the die is thrown once, the possible outcomes are 1,2,3,4,5,6 i.e., totally 6 out comes. Let E be the event of getting a number less than 5.
How many possible outcomes of a dice are there?
Ex15.1, 13 A die is thrown once. Find the probability of getting (i) a prime number; Total outcomes that can occur are 1, 2, 3, 4, 5, 6 Number of possible outcomes of a dice = 6 Prime number is a number not divisible by any number except itself Prime numbers on a dice are 2, 3, and 5.
What is the probability of getting a prime number on a dice?
Total prime numbers on a dice = 3 Probability of getting a prime number = (ππ’ππππ ππ ππ’π‘πππππ π€βπππ πππππ ππ’ππππ πππππ )/ (πππ‘ππ ππ’ππππ ππ ππ’π‘πππππ ) = 3/6 = 1/2 Ex15.1, 13 A die is thrown once.
How many elementary events are associated with the random experiment of throwing?
An unbiased die is thrown. What is the probability of getting: a number less than 5. In a single throw of a die we can get any one of the six numbers 1, 2., 6 marked on its six faces. Therefore, the total number of elementary events associated with the random experiment of throwing a die is 6.
