The answer is 27.3375%.
To calculate this, a multiplication rule is used. The multiplication rule calculates the probability that both of two events will occur. In this method, the possibilities of each event are multiplied.
So, we have three events occurring simultaneously:
1. set contains female singer: 45% = 0.45
2. set contains female singer: 45% = 0.45
3. set contains female singer: 45% = 0.45
Also, it should be taken into consideration that there are three set combinations:
female-female-male,
female-male-female,
male-female-female
So, the probability for one set of the song is:
0.45 × 0.45 × 0.45 = 0.091125
Therefore, the probability is multiple ways to achieve this pattern of songs):
3 × 0.091125 = 0.273375 = <span>27.3375%.</span>
First:
Divide everything by 9/5, or multiply by 5/9, in order to remove the multiply 5/9 from c.
This results in:
F(5/9) = c + 160/9
Then just move the 160/9 to the other side to get:
c = 5/9F - 160/9
Answer:
there is no x to solve, so there is no answer to that.
