Answer:
Step-by-step explanation:
This question is asking us to rewrite the original expression it in the form
First we have
By the law of exponents we know that when we are multiplying expressions that have the same base, we need to add up the exponents.
Thus, this would mean that, in order to multiply this expression, we need to sum up the exponents so we have:
Thus, this expression can be rewritten as:
Answer:
(A) 0.4196
(B) 0.2398
(C) 0.0020
Step-by-step explanation:
Given,
Total songs = 15,
Liked songs = 6,
So, not liked songs = 15 - 6 = 9
If any 5 songs are played,
Then the total number of ways =
(A) Number of ways of choosing 2 liked songs =
Since,
Thus, the probability of choosing 3 females and 2 males =
= 0.4196
Similarly,
(B)
The probability of choosing 3 liked songs =
= 0.2398
(C)
The probability of choosing 5 liked songs =
≈ 0.0020
