Abin contains beach balls. some beach balls have yellow on them. some beach balls have blue on them. some beach balls have yellow and blue on them. let y be the set of balls with yellow on them and b be the set of balls with blue on them.

what does p(y∪b)=6 mean?

There might be typo error. The probability of any quantity is always less than or equal to 1. So, the probability is not possible. It should be .

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,

Now, if , 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%.
