There might be typo error. The probability of any quantity is always less than or equal to 1. So, the probability [tex]P(Y\cup B)=6[/tex] is not possible. It should be [tex]P(Y\cup B)=0.6[/tex].
Answer:
It means that the probability of getting a yellow or blue ball is 0.6.
Step-by-step explanation:
Given:
Y = set of yellow balls
B = set of blue balls
Therefore, the union of both the balls is given by the set Y U B.
The set Y U B represents the set that contains either yellow balls or blue balls but do not contain those balls that have both yellow and blue on them.
So, [tex]n(Y\cup B)=n(Y)+n(B)-n(Y\cap B)[/tex]
Now, if [tex]P(Y\cup B)=0.6[/tex], it means that the probability of getting a ball that has either yellow or blue on it is 0.6. In other words, if there are 100 balls, then the chances of getting a ball having either yellow or blue on it is 60%.
