What is the probability of the event that a number chosen from 1 to 50 is prime number?
Step-by-step explanation: IN BETWEEN 1TO50 the prime numbers are 1,2,3,5,7,11,13,17,19,23,29,31,37,41,43,47 i.e, 16. probability is 16/50.
What is the probability of getting prime numbers between 1 to 30?
Prime numbers between 1 and 30 are 2 , 3 , 5 , 7 , 11 , 13 , 17 , 19 , 23 and 29. i.e. 10 / 30 = 1 / 3 . Hence , option (c) 1/3 is correct.
What is the 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.
When randomly choosing a number 1 30 What is the probability that you choose a multiple of 4 given that it’s an 3 even number?
Lily, The number of cards is given as 30. The number of cards that are multiples of 4: 4,8,12,16,20,24,28. In other words, 50\%.
What is the probability of getting a match on the first draw?
There is no way to get a match on the first draw. On the second draw, the probability of a match is 1/7. On the third draw, (assuming no match on the first) the probability is 2/6. On the fourth (if we get that far) it is 3/5.
What is the probability of a ticket being drawn from a box?
Tickets are drawn at random from the box without replacement until a number appears that has appeared before. Let X be the number of draws that are made. so the probability when X = 1 is: 4 ∗ 2 8 ∗ 1 7 which is 1 7 . when X = 2, in my understanding, the probability should be 4 ∗ 2 8 ∗ 6 7 ∗ 1 6, which is 1 7 again.
How many numbers can be drawn in Powerball?
The other number are anywhere between and including 1 to 25 and the last ticket will be from 24 other numbers between 1 to 25 as 1 ticket has been already drawn. Now the number of outcomes are not just 3000 but 9000, as the maximum number drawn can be second or third one.
