A drawer contains 6 red socks, 4 white socks, and 8 black socks. What is the probability you grab a red OR a black sock? (Make sure you know the total number of socks and simplify your answer)

Should be 7/9

Step-by-step explanation:

So you need to add 6 + 4 + 8 to get your probability then just add red plus black to get 14/18 and if you need to simplify it's 7/9 hope this helps

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
