Answer:
The probability is 0.026 to 3 d.p
Step-by-step explanation:
To calculate this , we shall be using the Bernoulli approximation.
let P = percentage of voters supporting the increase = 41% = 41/100 = 0.41
q = percentage of voters not supporting = 100-41% = 59% = 59/100 = 0.59
Now we want to calculate that exactly 15 out of 25 will vote in favor
Mathematically that would be ;
25C15 p^15 q^10
= 25C15 0.41^15 0.59^10
= 0.025981307443 or simply 0.026 to 3 decimal places

Step-by-step explanation: What do you mean by simplify?
Hey there,
To do this you need to work bout what 10% of 340 minutes is.
To do this do 340 / 10 = 34
34 is 10% of 340.
Now you should subtract the 10% from the original time.
340 - 34 = 306.
The answer is 306 minutes.
That was the long method. The short method is to use percentage multipliers.
To do this you do 340 x 0.9 = 306.
Either way you would get the same answer of 306 minutes.
Hope This Helps You!
Good Luck Studying :)
