Answer: A solid 4% chance of picking a yellow
brainliest plz
Step-by-step explanation: We first should combine 300 and 75 because those are the total values of the candies in the bag. After, we should divide the different candies by the total amount of them getting the numbers .8 for red and .2 for yellow. Since the question is that the yellow occurs but not the red and you can miss the bag you would want to calculate what the probability would be to have B happen but not A. The equation for that is:
(1 - P(A)) × P(B)
where P(A)=.8 and P(B)=.2
plugging in all things it would be
(1-.8)*.2
which equals .04 or 4%

Answer:
f^-1(x) = 9x+18
Step-by-step explanation:
To get the inverse of a function, we exchange x and y then solve for y
y = 1/9x -2
Exchange x and y
x = 1/9y -2
Add 2 to each side
x+2 = 1/9y-2+2
x+2 = 1/9y
Multiply by 9
9(x+2) = 9*1/9y
9x+18 = y
f^-1(x) = 9x+18
