Answer:
The theoretical probability of obtaining exactly four heads when flipping six coins is also 23.4%.
Step-by-step explanation:
Getting x successes out of n trials is a binomial distribution and is given by:
p(x) =
Here, n = 6
x = 2
p = probability of one head =
q = 1 - p
=
=
Substitute these values, we get,
p(2) =
=
=
= 0.234
= 23.4%
We know that
Now,
p(4) =
=
= p(2)
Hence, the theoretical probability of obtaining exactly four heads when flipping six coins is also 23.4%.
Answer:

I think it's just 5/63. Not 100% sure
Answer:
f(x - 2) = 8x - 16
Step-by-step explanation:
f(x) = 8x
f(x - 2) = 8(x - 2)
f(x - 2) = 8x - 16
