You have a set of 36 flash cards numbered from 1 to 36. A card is chosen at random. Find the odds in favor of and the odds againts each selection.
Prime number
Would it be 1?
i think your asking what the odds are that you will pick a odd number if picked from 36 cards numbered 1-36 if so 1 is pime 2 is prime 3 is prim 5 is prime 7 is prime 11 is prime 13 is prime 17 is prime 19 is prime 23 is prime 29 is prime 31 is prime and that's it so that means out of the 36 numbers you have 12 are prim so the probubility of picking a prim number out of the 36 is 1/3 because you reduse it
If random, the odds of picking a particular card = 1/36, while the odds of not picking a particular card = 35/36.
To find the odds in favor of and the odds against selecting a prime number from the set of cards, we first need to determine the total number of prime numbers in the set.
Prime numbers are whole numbers greater than 1 that only have two factors: 1 and the number itself. The prime numbers from 1 to 36 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31.
There are a total of 11 prime numbers in the set of 36 cards.
To calculate the odds in favor, we can use the following formula:
Odds in favor = Number of favorable outcomes / Number of unfavorable outcomes
In this case, the favorable outcome is selecting a prime number, which has a count of 11. The unfavorable outcome is selecting a non-prime number, which would be the remaining numbers from 1 to 36 minus the 11 prime numbers, resulting in 36 - 11 = 25 unfavorable outcomes.
Odds in favor = 11 / 25
To simplify the fraction, we can divide both the numerator and denominator by their greatest common factor, which is 1 in this case.
Odds in favor = 11 / 25
The odds against can be obtained using the reciprocal of the odds in favor:
Odds against = 1 / Odds in favor
Odds against = 25 / 11
Therefore, the odds in favor of selecting a prime number is 11 / 25, and the odds against selecting a prime number is 25 / 11.
