P(blue) = 1/3
Step-by-step explanation:
Probability for any event A is given by
p(A) = no of times of happening of event A/ total no of occurrence of all the events given under the situation.
A bag contains 5 blue marbles, 6 red marbles, and 4 green marbles
So, total no of occurrences of all the events given under the situation
one can either pick blue, red, or 4 green marbles
Total no. of occurrence of all the event = 5 + 6 + 4 = 15
Now, no occurrence of selecting blue.
since there are 5 blue marbles, there is a chance of selecting blue as 5.
no occurrence of selecting blue = 5
Therefore,
P(blue) = no of occurrence of selecting blue /total no of occurrence of picking any color ball
P(blue) = 5/15 = 1/3.
