A number is picked from the set p:{2,3,4,5,___9} find the probability that the number is prime.
prime in set: 2,3,5,7
numbers in set: 2,3,4,5,6,7,8,9
pr(prime)=4/8=.5
To find the probability that the number picked from the set is prime, we first need to determine the number of prime numbers in the set p:{2,3,4,5,___9}.
The prime numbers in the given set are 2, 3, and 5. Therefore, there are 3 prime numbers in the set.
Next, we find the total number of elements in the set, which is 5.
Therefore, the probability that the number picked is prime is given by:
Probability = Number of favorable outcomes (prime numbers) / Total number of possible outcomes
Probability = 3/5
Thus, the probability that the number picked from the set is prime is 3/5.
To find the probability that the number picked from the set p:{2, 3, 4, 5, ___, 9} is prime, we need to first determine how many prime numbers exist in the set.
The prime numbers in the set are 2, 3, and 5.
To find the probability, we divide the number of favorable outcomes (prime numbers) by the total number of possible outcomes (numbers in the set).
The favorable outcomes (prime numbers) are 2, 3, and 5, which are a total of 3 numbers.
The total number of possible outcomes is the number of numbers in the set p, which is 5.
Therefore, the probability that the number picked is prime is 3/5.
In general, to find the probability of an event happening, you divide the number of favorable outcomes by the total number of possible outcomes.
