Assuming they're numbered the way you're implying, you have a 2 out of 3 chance (2/3, 6/9) of getting an even tile. That's 66.66666666etc
Pick a number
Put the numbers in numerical order, pick the middle number. If there is an even number of numbers, pick the middle two, and find the mean of them. So in this case, the middle two numbers are 4.8, and their mean (4.8+.48 divided by two) is [u][b]4.8[/u][/b]
one
we cannot find the exact quantity as the total vehicles are not given only the white are given
from 1-9 have 9 numbers so that we have 9*9*9*9*9=59049 Consider the case of 5-digit number combinations, where each is some digit from 1 through 9. There are 9 different digits you can pick for the first number. Assuming you can have repeats, there are 9 you can pick for the second, 9 you can pick for the third, and 9 you can pick for the fourth and 9 you can pick for the fifth.
What is the probability that the second tile you pick is yellow? (didnt have enough space to finish the question)
Probability tells you the chance that something will happen. For example: There are 3 red tiles, 5 green tiles and 2 pink tiles in a bag. What is the probability of picking a red tile? First you find out how many red tiles there are. There are 3 red tiles. Then, you add up all the tiles. Altogether there are 10 tiles. So, there is a 3/10 probability that you will pick a red tile.
So I guess the counters are numbered 1 through 7, and you pick one of them. There are 7 possibilities, 3 of them are even numbers {2,4,6}, so the probability is 3 out of 7. 3/7 = approx. 42.86%
From 75 to 100 (inclusive), there are 26 numbers, and 13 of them are odd.The probability of picking an odd number is 13/26 = 50%.
It is 14/20 or 7/10.
When you pick an object and do not return it, in probability it is termed "without replacement".
If you pick 37 cards without replacement, or pick a card from the bottom of a mint deck, the probability is 1: it is a certainty. If you pick a random card from a deck, then the probability is 4/13.
There are 20 numbers from 20 through 39, and 4 of them are prime (23, 29, 31, 37), the probability is 4 in 20 or 0.20.
All players throw their tiles back and pick 7 new tiles.
7/26
no. because there are more composite numbers than prime numbers It depends on the place you choose to pick the prime number (e.g. 457 or 7577?). The bigger the number the less likely it is a prime.A formula gives the probability for a number being prime (Prime Number Theorem).
Pr(Both picked 3) = 1/16Pr(Both picked the same) = 1/4.
