Step-by-step explanation:
Here is a problem with the concept of properties of the exponent.
We are given and we have to find the value of 5x.
Now, {Since we are given that
}
⇒ {Since we can write
}
⇒ {Since we know the formula of exponent as
}
(Answer)
Solution:
we are given that
A number picked at random from the numbers 1 through 15 is prime.
As we know the number between 1 and 15 which are primes are listed below
2,3,5,7,11,13.
Here total number of favourable outcomes are 6.
The numbers 1 through 15 are as below:
1,2,3,4,5,6,7,8,9,10,11,12,13,14,15.
Here total number of possible outcoes are 15.
Hence the probability that if a number picked at random from the numbers 1 through 15 is prime
Hence the probability that if a number picked at random from the numbers 1 through 15 is prime is 0.4
