    CIE vs EDEXCEL

    i think there are like wayy more online/print resources for cie than for edexcel... so it's easier to prep for cie... plus i somehow can't understand any questions in edexcel past papers. like, i get confused about what they're asking. so i guess it matters what format you're used to.

    STATS question!

    to find Σ(x − 50): We know Σ(x)=824. and the total number of students is 16. So Σ(x − 50)= Σ(x) - (16 x 50) = 824 - 800 = 24. to find Σ(x − 50)^2: we know the formula for variance, so substitute the values in it. So you get (Σ(x − 50)^2)/16 - (Σ(x − 50) / 16)^2 = (6.5)^2 using simple algebra...

    Stats question (Paper 6)

    225 out of 900 have more than 1002 ml therefore P(X>1002)= 0.25 ==> P(X<1002)= 0.75 z<(1002-mean)/sd from the table of normal distribution, in the critical values table, we get P= 0.75 when z=0.674 so 0.674(8) = 1002 - mean mean = 996.608 or 997

    Maths P62 question

    how can you guess a stats paper?? and isn't it just easier to revise everything? like you know for sure permutations and combinations will come... do a few random questions on that. it's more productive than wasting time making guesses that prolly won't be true anyway...

    stats

    from the table, you can see that the total number of students is 194. out of these, (30 + 30)= 60 take between 7 to 10 minutes. one student takes 7-10 minutes from the two students chosen at random. number of ways the one student can be chosen is 2C1 also note that this case is without...

    Stat Help

    you get the part where at least two friends means either 2 or all 3 friends use the same entrance B? so P(at least 2 friends)= P(2 friends) + P(3 friends) we know the three friends are Ali, Brenda, and Rick. so if all three go through entrance B, P= 2/9 x 1/4 x 2/35= 1/315 if two go through...

    Stat Help

    okay, so the question asks for the probability that AT LEAST 2 friends choose entrance B. that means either 2 or all 3 of them choose entrance B. for 2 friends, the combinations can be: B B other Rick Brenda Ali Ali Rick Brenda...
