17 Reuben throws a biased coin 10 times.
He gets 6 Tails
Jacob throws the same coin 100 times.
She gets 65 Tails
Miriam is going to throw the coin once.
Whose results will give the better estimate for the probability that she will ge Tail
Reuben's or Jacob's?
You must give a reason for your answer.
a
(1)
(ii) Use Reuben's and Jacob's results to work out an estimate for the probability that
Miriam will get Tails

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
