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 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
