Have a Great Day <3
Step-by-step explanation:
N = # of chips = 100
M = # of defective chips = 8
S = sample size = 10
a) P(X ≥ 1) = 1 - [((N-M)! / (N-M-S)!) / (N! / (N-S)!)] ≈ 0.583
b) P(X = 10) = 0 (because S > M)
c) P(X = 9) = 0 (because 9 > M)
d) P(X = 0) = 1 - P(X ≥ 1) ≈ 0.417
Answer:
1) -12 + 5 = -7 you just set it up and solve it like a regular problem and then to see if its a - or + we see what number was bigger so -12 is bigger then +5 so our answer is -7
2) 7 -3 + 15 - 2 - 3 + 6 so lets add up all the negative numbers and all the positive numbers so now we have + 28 - 8 so the we solve +28 - 8 = +20 again the sign goes with the bigger number!
Hope this helps!!! Good luck!!! ;)
