Stat v. 62
I got 0.25, 0.175 and 0.575 as the probabilities.. but I kinda feel I've messed up somewhere. Yeah, I don't think they would penalise you since the format wasn't mentioned in the question. You're talking about AS chemistry practical right? I did that on 14th May! It was pretty lengthy but not... -

Lol.. those are the values of X. What did you get the probabilities for each? -

(iii) Mutually exclusive events are those which do not contain any shared events i.e nothing common between the two. If you look closely, the product of two numbers can not be 24 (Event Q) if both the numbers are greater than 8 (Event R). Hence, they are exclusive! (iv) If two events are... -

Firstly, you are supposed to compare the medians of both the countries as a measure of central tendency. 1/2 of 900 = 450. To find the median, draw a horizontal line from the 450th point on the vertical axis until it meets the curve. Then move down from that point until it reaches the x-axis... -

The probability of getting more than 1002mm, P(X>1002), is 225/900 = 1/4 Therefore, P(X < 1002) = 1 - 1/4 = 0.75 From the probability table, z = 0.674 (When probability is 0.75). Standaridising, (1002 - µ)/8 = 0.674 After doing the calculations, you'll get µ = 997. Hope that helped :) -
