Answer:</h2>
<u>The pressure will be 176 k Pa</u>
<h2>
Step-by-step explanation:</h2>
Boyle's law states that the product of volume and pressure gives us a constant value so we can write the expression as
P1V1 = P2V2
By arranging the equation we get
P1V1 / V2 = P2
Putting the values
(132 x 20 ) / 15 = P2
P2 = 176 k Pa
Answer:
Total no. of buttons = 300 + 700 + 1000
+ 500 = 2500
Possibility for a person to pick a pink button = 300/2500 = (3/25)%
