15 from 49
There are 15 primes from 1 to 49 (including '1').The probability is (15/49) = 30.612 %(rounded)
The probability of a prime number in a random pick from the numbers 1-49 is 15 in 49, as there are 15 prime numbers (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43,and 47) in the range of 1 to 49.
Probabilities can only range from 0 to 1. All of the options range from 0 to 1 (14% is the same as 0.14) except -49, so -49 is not a probability.
Since 49 is a composite, the answer is 0.
Assuming the questions are answered at random, the probability is 0.000009, approx.
You collect data. Flip a coin 100 times, you get 49 heads and 51 tails, so the probability of H is 0.49.
The probability the shooter makes both shots is .7 * .7 = .49, and the probability of making neither is .3 * .3 = .09. So the probability of making exactly 1 out of 2 is 1 - .49 - .9 = .42, or 42 percent.
15/49ExplanationThere are 15 prime numbers between 1 and 49 (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47). If you randomly choose one natural number from the 49 numbers between 1 and 49 inclusive, there is a 15/49 probability that it will be prime.
(3/7)*(2/7)=(6/49) You have a 6 out of 49 probability.
49/9000
No, it's not a probability since it's not set in terms of ratio of two values, such that the second value is greater than the first. For instance: 1 to 2 or 1 / 2. Also, probability is never negative.
