1. Step-by-step explanation:

p(B) =favourable outcome/total outcome

=5/11

2. Answer:

## Given:–

A bag contains 6 red ball’s and 5 blue ball’s one ball is drawn of random from the bag, what is the probability of getting a blue ball.

## ToFind:–

Probability of getting a blue ball.

## Note:–

Probability = $$\frac{Number \ \ of \ \ favourable \ \ outcomes}{Total \ \ Number \ \ of \ \ outcomes}$$

Here, Number of favourable outcomes is the bag contain balls for which ball we are finding, Total number of outcomes is total number of balls.

## Solution:–

$$\huge\red{First, calculating \ \ missing \ \ values}$$

### • Here, Number of favourable outcomes = 5 balls; Total number of outcomes = ?

According to note second point~

▪︎$$Total \ \ number \ \ of \ \ outcomes = Total \ \ number \ \ of \ \ balls ( red + blue \ \ balls )$$

▪︎$$Total \ \ number \ \ of \ \ outcomes = 5 + 6 \ \ balls$$

▪︎$$Total \ \ number \ \ of \ \ outcomes = 11 \ \ balls$$

$$\huge\green{Total \ \ number \ \ of \ \ outcomes = 11 \ \ balls}$$

## ______________________________________________

$$\huge\red{ Now, we \ \ will \ \ calculate \ \ Probability }$$

### • Number of favourable outcomes = 5 balls, Total number of outcomes = 11 balls, Probability = ?

According to note first point~

▪︎$$Probability = \frac{Number \ \ of \ \ favourable \ \ outcomes}{Total \ \ number \ \ of \ \ outcomes}$$

▪︎$$Probability = \frac{5 \ \ balls}{11 \ \ balls}$$

Here, calculations can’t be done so simply leave it and balls-balls will be canceled~

▪︎$$Probability = \frac{5}{11}$$

$$\huge\green{Probability = \frac{5}{11}}$$

## Answer:–

Hence, the Probability of getting blue ball is = $$\frac{5}{11}$$.
