You can find this out just like you'd find out what % grade you got on a test. Divide 48 by 70 and you'll get the answer of .0685 or 69% rounded up (not lying, actually 69%)

The odds of an individual getting struck by lightening in one year are roughly 1 in a million; for this question assume this pro

Montano1993 [528]

Answer:

There is a $5*10^{-9}$ % probability that exactly 2 of them are hit by lightening in a given year

The correct probability distribution to solve this problem is the binomial probability.

This is exact the type of problem that the binomial probability is used, when we want to find the probability of a exact number of events happening in a number of trials.

Step-by-step explanation:

Here we use the binomial probability.

For the binomial probability calculus we have these following parameters.

$n:$ The number of repeated trials

$x:$ The desired number of sucesses.

$p:$ The probability of success on each individual trial.

The probability of exactly x sucesses on n repeated trials is given by:

$P = C_{n,x}.p^{x}.(1 - p)^{n-x}$

In which $C_{n,x}$ is the combination of the number of repeated trials and the desired number of sucesses. The combination formula is given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Here we have:

Sample of eleven people, so $n = 11$

Exactly two of them being hit, so $x = 2$

$p = 10^{-6}$

The probability that exactly two people are hit by a lightning is:

$P = C_{n,x}.p^{x}.(1 - p)^{n-x}$

$P = C_{11,2}.(10^{-6})^{2}.(1 - 10^{-6})^{9}$

$P = 55.(10^{-6})^{2}.(1 - 10^{-6})^{9}$

$P = 5*10^{-11}$

Multiplying by 100, to write in percent notation.

There is a $5*10^{-9}$ % probability that exactly 2 of them are hit by lightening in a given year
