the probability of the event choosing a yellow marble is 2/9 .
<u>Step-by-step explanation:</u>
Here we have , to choose a marble from a jar. The jar contains 4 red
marbles, 10 blue marbles, 7 green marbles, and 6 yellow marbles. We need to Find the probability of the event choosing a yellow marble . Let's find out:
According to question question we have following parameters as :
Red marbles = 4
Blue marbles =10
Green marbles = 7
Yellow marbles = 6
Now , Probability to chose a yellow marble is :
Favorable outcomes = 6(Number of yellow marbles )
Total outcomes = 4+10+7+6 = 27( Total marbles )
Hence ,
⇒ 
⇒ 
Therefore , the probability of the event choosing a yellow marble is 2/9 .
I think it’s B I’m sorry if I’m wrong
Try to imagine this word problem, there is a wall and a ladder leaning against it, the space from the bottom of the ladder is labeled 6 and the length of the height the ladder reaches on the wall is 8. Imagine this as a right triangle now, where the length of the ladder is the hypotenuse and the length of the legs of the triangle is 6 and 8. Because we know this, we can use the Pythagorean theorem, a^2+b^2=c^2
We then plug in the values and you get 6^2+8^2=c^2
When you simplify, you get 36+64=c^2 which is c^2=100
When you solve for c, you get c=10 which would be the length of the ladder :)
Well 31 is not able to go any were and it has to stay 31
hope this is ans . Brother
