There are yellow cubes blue cubes and green cubes. There are three times as many blue cubes then yellow cubes and there are five times as many green cubes then blue cubes. What is the probability that a yellow cube is chosen write your answer as a fraction

1/19

Step-by-step explanation:

Let yellow cubes be x

Let blue cubes be x

Let green cubes be x

So let's interpret the question

3 times of blue than yellow means

3xx

Fives times of green than blue which means 5(3x)

15x

So blue is 3x, yellow is x and green is 15x

Let's sum them up

3x+x+15x=19x

Probability of yellow is

x\19x

1/19

Since we are to leave our answer in fraction therefore the final answer is 1/19

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
