Given that A and B are two
independent Events
where P(A) = (4/5) and
P(A ∪ B) = ((13)/5) .
find a) P(A∩B)
b) P(A∣B).
hence draw tree Diagram
for each posible out come
Given the lines
l_1 : x + y = 5 and l_2 : y = 4x
and l_3 ; 4x + y − 1 =0
show that l_(2 ) is perpendicular
to l_3 .
find the point coordinates
if x + 2y = 5 is colliner to l_1
Given the matrices
A = ((3,5),(2,4) ) and I = ((1,0),(0,1) )
find matrix B if
BA= I
find A′ the reflection on the
line y = x and A′′ the enlargement
with matrix (((2 0)),((0 2)) ).
Given a polynomial f(x) where
f(x) = x^3 + ax^2 + 3x + b
and ( x− 1) is a factor of f(x)
and f ′(x)= 12 at point ( 2,4)
find the values of a and b
hence factorise f(x) completely
