What is the probability that a randomly selected number from 15-27 is prime?

1 answer:

8 0

Answer: As we know that, Probability of an event =Number of favourable cases Number of total cases, We get, probability of choosing a prime number from 1 to 20 =820=25. Therefore, we get the probability of choosing a prime number from 1 to 20 as 25or 0.4.

Answer:

Soln:

Step-by-step explanation:

Here,

Base(b) =9

Opposite/Perpendicular (p)= x

Hypotenus (h) = 24

We know,

(p)^2 = (h)^2 - (b)^2

(x)^2 = (24)^2 - (9)^2

x^2 = 576 - 81

x^2 = 495

x = root under 495

What ks the % of 4 = 2

Fittoniya [83]

Answer:

$50\%$

Step-by-step explanation:

Let x be the percentage then...

$x\%(4)=2$

Start by dividing both sides by 4:

$x\%=\frac{2}{4}$

Simplify the fraction:

$x\%=\frac{1}{2}$

Then, multiply the fraction by 50/50, so we can get a number over 100 (that number would be the percentage). Note we can only multiply it by 50/50 since it is essentially multiplying the fraction by 1.

$x\%=\frac{1}{2}*\frac{50}{50}\\x\%=\frac{50}{100}\\x=50\%$
