The probability of rain =0.2, sun=0.3,cloud=0.5. What is the probability of rain and sun over a two day period?

svp [43]

Answer:

0.2752512

Step-by-step explanation:

The formula you are looking for is the binomial probability:

P (X) = ------------ * (P)^X * (q)^n - X

(n- X)! X!

For your particular problem:

n=7

X=2

q = 1-p = .8

7!/(5!*2!)*(.2)^2*(.8)^5 = 0.2752512

Hope this helps, have a nice day/night! :D

A right rectangular prism has edges of 8 feet, 4 feet, and 1/2 foot. How many cubes with side lengths of 1/2 foot would be neede

Ksenya-84 [330]

Answer:

Step-by-step explanation:

From the question we are told that

Edges of 8 feet, 4 feet, and 1/2 foot

Generally the volume V_p of the right rectangular prism is mathematically represented as

$V_p=8*4*0.5$

$V_p=16$

Generally volume of the cube V_c is mathematically given as

$V_c =(\frac{1}{2})^3$

$V_c =\frac{1}{6}$

Therefore total number of cubes is given as

$V=\frac{V_p}{V_c}$

$V=\frac{16}{\frac{1}{6}}$

$V=96$
