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%.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

its line 2 i just added the rest or else it wouldn't let me answer
