The probability to choose letter n is \frac{1}{26}. After drawing letter n there left 25 letters and the probability to choose the letter w is \frac{1}{25}. After drawing two letters n and w there left 24 letters and then the probability to choose letter b is \frac{1}{24}. After drawing three letters n, w and b there left 23 letters, so the probability to choose letter t is \frac{1}{23}.
Using the product rule for probabilities, you can obtain that P= \frac{1}{26} * \frac{1}{25} * \frac{1}{24}* \frac{1}{23} =0.0000027.

What is the area of the circle?
Bumek [7]

Answer:

363

Step-by-step explanation:

Formula for area of a circle

A = πr^2

Where r = radius

The circle has a given radius of 11

To find the area of the circle we simply substitute r in the formula with the value of the radius (11)

( Also note that the question says to use 3 for π )

A = πr^2

π = 3

r = 11

Substitute values in formula

A = (3)(11)^2

11^2 = 121

A = 121(3)

121(3) = 363

A = 363
