probability in Mathematics OR Explain how do you calculate probability ? Given: Numbers \( 1,2,3, \ldots, 15 \) are given. To do: We have to find the probability that a number selected from the numbers \( 1,2,3, \ldots, 15 \) is a multiple of 4. Solution: Numbers \( 1,2,3, \ldots, 15 \) are given. This implies, The total number of possible outcomes $n=15$. Multiples of 4 from 1 to 15 are 4, 8 and 12. Total number of favourable outcomes $=3$. We know that, Probability of an event $=\frac{Number\ of\ favourable\ outcomes}{Total\ number\ of\ possible\ outcomes}$ Therefore, Probability that a number selected from the numbers \( 1,2,3, \ldots, 15 \) is a multiple of 4 $=\frac{3}{15}$ $=\frac{1}{5}$ The probability that a number selected from the numbers $1, 2, 3, ........, 15$ is a multiple of 4 is $\frac{1}{5}$. The probability that a number selected at random from the numbers 1, 2, 3, ..., 15 is a multiple of 4, is `(A)4/15` `(B)2/15` `(C)1/5` `(D)1/3` Advertisement Remove all ads SolutionCorrect answer: C Concept: Basic Ideas of Probability Is there an error in this question or solution?

Total number of possibilities = 15. Multiple of 4 are { 4,8,12} Number of favourable out comes = 3 Probability that a number selected at random from the numbers is a multiple of 4 =315=15 answer:- (c) 15What is the probability that a number selected at random from 1 2 3 15?answer:- (c) 15. What is the probability that a number selected from the number 1 to 20 is a multiple of 5?If one number is randomly selected between 1 and 20, what is the probability that the number is a multiple of 5? The answer is 1/6. Those numbers are 5,10,15 (as we exclude 1 and 20). So probability is 3/18=1/6. What is probability that a number selected at random from the numbers 1 2 3 99100 is a prime?99,100 is a prime is. =0.25. Was this answer helpful? What is the probability that a number selected at random 1/22 333 4444 will be average?∴ required probability (of getting 3 as average) = No. of favorable outcomestotal No. of outcomes=310=0.3. What is the probability of getting a multiple of 3 from 1 to 20?Complete step-by-step answer:
Numbers on the card are: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20. Now, let us find the probability of getting a multiple of 3. Multiple of 3 between 1 to 20 are 3, 6, 9, 12, 15, 18.
Is there an even multiple of 3 from 1 to 20?Write the multiples of 3 between 1 and 20? The multiples of 3 between 1 and 20 are 3, 6, 9, 12, 15 and 18.
What is the probability that a number selected from 1 to 20 is a multiple of 5?If one number is randomly selected between 1 and 20, what is the probability that the number is a multiple of 5? The answer is 1/6.
What is the probability that the number is a multiple of 3?Hence, the probability of getting a multiple of 3 when a die is thrown is 1/3. Was this answer helpful?
