AI Thread Summary
The discussion focuses on calculating the probability of finding small tomatoes in a random sample from a farm where 2.3% of cherry tomatoes are deemed unsellable. Two specific probabilities are requested: the likelihood of selecting 3 unsellable tomatoes from a sample of 12, and the probability of selecting at least 4 unsellable tomatoes. The calculated answers are approximately 0.217 for the first scenario and 0.012 for the second. Participants encourage sharing the friend's attempts to better assist with the calculations. The thread emphasizes the need for detailed working out to aid understanding.

it is estimated 2.3% of the cherry tomatos fruits produced on a certain farm are considered to be small and cannot be sold for commercial purposes. The farmers have to separate such fruits and use them for domestic consumption instead.
a) 12 tomatoes are randomly selected from the produce, Calc
i) the probability that 3 are not fit for selling
ii)the prob that atleast 4 are not fit for selling


answers are a i) 0.217 ii) 0.012

how do I get them? I need full working out! thanks its for studying!


-- Not for me but posting for a friend who can't figure out how to get the answer. Thanks

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
