Hi JC/A-Level Mathematics Tuition Students Singapore

Hi Wei Ren

N88/II/6

a) P(all the four cards are different) = (10x9x8x7)/(10x10x10x10) = 63/125

b) Since the first three are different. He has 10x9x8 choices. The fourth card is the same as either one of the first 3 cards, therefore he has 3 choices. Althogether he has 10x9x8x3 choices.

P(exactly 3 different pictures out of a total of four cards) = (10x9x8x3)/10^4 = 27/125

c) Required probability = 1 – P(all the four cards does not contain X or Y)= 1- (8/10)^4 = 0.591

d) P(n more cards are needed) (9/10)^n-1 x (1/10)
P( at most n more cards are needed) = 1/10 + (9/10)(1/10)………..(9/10)^n-1 x (1/10)

This is sum of GP

1- (9/10)^n > 099
n > 43.7

least value n = 44

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!

Hi J1 Students

To find the inverse of y = x – 1/x
Multiply the equation by x
xy = x^2 -1
x^2 – yx – 1 = 0
using x = -b +- Sq rt( b^2 – 4ac) divide by 2a

x = y +- sq rt ( y^2 – 4.1.-1) divide by 2
= y +- sq rt ( y^2 + 4)divide by 2
