Hi JC/A-Level Mathematics Tuition Students Singapore
4 common errors in Normal Distribution
1) Remember to sq root your variance when using GC
2) For two independent events, variance is always ADD
3) 2X + 3Y, remember to square the number 2 and 3 when finding the variance
4) X1 + X2 + X3, when finding the variane, just add them together
Cheers!
