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 .
