A manufacturer has shipped 51 cameras to an electronics​ store, of which 3 are defective. If the electronics store sold 28 cameras before discovering that some were​ defective, what is the probability that at least one defective camera was​ sold?

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it
