7) The length of glass plates are measured to the nearest tenth of mm. The lengths are uniformly distributed between 590.0 and 590.9
i. If we select a sample of 10 plates, what is the probability that less than 4 of them have length under 590.3?
ii. If we select a sample of 10 plates, what is the probability that 9 of them have length greater than the mean length?
iii. If we select 10 plates, what is the probability that only two have length greater than 590.6?

thanks in advance
