Probaility tree diagram question
if working out is needed use : )

A = 9/10

b = 1/3

c = 2/3

I dunno how to explain it properly but the question gives the fractions, you just need to find out what makes the other fraction that can equal to 10/10 for the first part, then 3/3 for the second part.

3x - 12

(Let me know if I was right, though I kinda just simplified it)

Step-by-step explanation:

3(x - 5) + 2

Given

3x - 15 + 2

Distributive property (Multiply the 3 with the x and the -5.  3 times x = 3x and 3 x - 5 = -15)

3x - 12

Combine Like Terms (-15 and 2 are like terms, as they both don't have exponents or variables. Since 15 is a negative in this and 2 is positive, we are basically subtracting. -15 + 2 = 12.)
