A drawing class was assigned a final project where students had to choose one art medium and one subject. The teacher kept track of the types of projects submitted. The probability that a student used chalk is 0.3, the probability that a student chose to draw a plant is 0.6, and the probability that a student used chalk and chose to draw a plant is 0.2.
What is the probability that a randomly chosen student used chalk or chose to draw a plant?

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
