(1) @born 0. 27
My mum was 27 when I was born.
(2) now-8. x-8. y-8
(3) now. x y
(4) now+5. x+5. y+5

(1)&(3). y-x = 27-0 = 27

8 years ago she was twice as old as I shall be in 5 years time.
(2)&(4). y-8 = 2(x+5)

2 variables 2 equations ... solve x
x = 9, y = 36

If P(E) = 0.32, then what are the odds against E?
steposvetlana [31]

Answer:

0.68 : 0.32

Step-by-step explanation:

the probability of all the outcomes of an event is always 1 .

if P(E) = 0.32,

P(E') = 1 - 0.32

= 0.68

N.B that P(E') is the same as P( not E ).

since your answer should be given in the ratio form, as the odds against E ( probability not E : probability E),

P(E') : P(E)

0.68 : 0.32

hope this helps you!
