Answer 1

Answer:

5/11

Step-by-step explanation:

There can be 11 results because of 11 balls. So 5 blue balls are there, and out of 11 balls, you can not have more than 5 balls. that's how probability is calculated.

Answer 2

Answer:

=>S={6+5}

=>S={11}

=>n(s)=11

Therefore let the event of getting blue ball be A

=>A={5}

=>n(a)=5

=>P(A)=n(a)

_____

n(s)

=>P(A)=5

___

11
