What is the probability of getting a two digit number?
There are 90 two digit numbers(99–9). Out of this there are 6 numbers divisible by 15(15, 30, 45, 60, 75, 90), which are also divisible by 5. Therefore, the favorable cases are 30–6=24. Hence, the required probability is 24/90 = 4/15.
What is the probability of choosing neither odd nor Prime?
A number is chosen random from 1-50 what is the probability of not selecting odd or prime numbers? – Quora. 48\%.
What are the prime number less than 50?
The numbers below 50 are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49. A prime number is a number which has only two factors 1 and itself.
How many prime numbers are there between 1 and 50?
Therefore, the prime numbers between 1 to 50 are 1, 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, and 47.
What is a probability of the event that a number chosen from 1 to 100 is a prime number?
We need to find the probability of even choosing a prime number from 1 to 100. Therefore, total prime numbers from 1 to 100 are = 25. Hence, the probability of the event that a number chosen from 1 to 100 is a prime number is $$\dfrac{1}{4}$$. Therefore, option (3) is the correct answer.
What is the probability that a randomly selected 2 digit number would be a multiple of 3 but not of 5?
Probability that a two-digit number is a multiple of 3 and not a multiple of 5 = 30-6 = 2490= 415.
What is the probability that a leap year will have 53 Sundays?
The probability that a leap year selected at random contains 53 Sunday is (1)7/366 (2)28/183 (3) 1/7 (4) 2/7. We know that a leap year has 366 days. So, we have 52 weeks and 2 days. Hence, a leap year has 52 Sundays.
What is the probability of choosing an odd number?
Favourable possibilities are: 1 or 3 or 5 or 7 or 9. (Total 5 possibilities). Therefore Probability = 5 / 10 = 1/2 or 50\%.
How many prime numbers are there between 11 and 50?
The prime numbers less than 50: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47.
How many prime numbers are there between 2 and 50?
