If five numbers are selected at random from the set {1,2,3,...,20}, what is the probability that their minimum is larger than 5?

Zanzabum

Answer:

the probability that their minimum is larger than 5 is 0.2373

Step-by-step explanation:

For calculate the probability we need to make a división between the total ways to selected the 5 numbers and the ways to select the five numbers in which every number is larger than 5.

So the number of possibilities to select 5 numbers from 20 is:

20 * 20 * 20 * 20 * 20

First number 2nd number 3rd number 4th number 5th number

Taking into account that a number can be chosen more than once, and the order in which you select the numbers matters, for every position we have 20 options so, there are $20^{5}$ ways to select 5 numbers.

Then the number of possibilities in which their minimum number is larger than 5 is calculate as:

15 * 15 * 15 * 15 * 15

First number 2nd number 3rd number 4th number 5th number

This time for every option we can choose number from 6 to 20, so we have 15 numbers for every option and the total ways that satisfy the condition are $15^{5}$

So the probability P can be calculate as:

$P=\frac{15^{5} }{20^{5} } \\P=0.2373$

Then the probability that their minimum is larger than 5 is 0.2373

Tim plays a computer game. each game is a win or loss

Drupady [299]

Answer:

If the rest of the question is:

Each game is a win or a loss.

He wins three fifths of his first 40 games.

He then wins his next 12 games.

For all 52 games, work out the ratio wins : losses

Give your answer in its simplest form.

then the answer is below ↓

Step-by-step explanation:

9:4

of his first 40 games: 3/5 *40=3*8=24 wins

=> of his first 40 games: 24 wins and 40-24=16 losses

next 12 games: 12 wins

so, for all 52 games: 24+12=36 wins and 16 losses

36 wins and 16 losses

wins: losses=> 36:16=> 9:4

What is m∠A ? Enter your answer in the box |___|

Ilya [14]

We know that the sum of all angles in a triangle = 180°

Angle (A+B+C) = 180°

or

(3x°+13) + (x°-8) + x° = 180

5x° + 5 = 180°===> 5x° = 175° & x =35°
