Answer:
0.1
Step-by-step explanation:
total number of marbles= 2+4+8=14 marbles
probability of getting 2blue
= 4/14×3/13= 4×3/14×13=12/182= 0.06593
to the nearest tenth= 0.1
Answer:
The inverse of the function is .
Step-by-step explanation:
The function provided is:
Let .
Then the value of <em>x</em> is:
For the inverse of the function, .
⇒
Compute the value of as follows:
Hence proved that .
Compute the value of as follows:
Hence proved that .
Let's say you want to compute the probability
where
converges in distribution to
, and
follows a normal distribution. The normal approximation (without the continuity correction) basically involves choosing
such that its mean and variance are the same as those for
.
Example: If
is binomially distributed with
and
, then
has mean
and variance
. So you can approximate a probability in terms of
with a probability in terms of
:
where
follows the standard normal distribution.
