Question

There are 30 blue balls, 40 red balls, and 30 white balls in a bag of balls. What is the conditional probability of choosing a blue ball, given that a white ball was not chosen?

Answer 1

Answer:

So, only 70 balls are left with us , from which we choose a blue ball

So, the probability will be

P( \text{getting a blue ball })=\frac{30}{70}=\frac{3}{7}

Step-by-step explanation:

Answer 2

Answer: So, the probability will be

$P( \text{getting a blue ball })=\frac{30}{70}=\frac{3}{7}$

Step-by-step explanation:

Since we have given that

Number of blue balls =30

Number of red balls = 40

Number of white balls = 30

Since there are 100 balls in total ,

As we have given that there is no white ball chosen.

So, only 70 balls are left with us , from which we choose a blue ball

So, the probability will be

$P( \text{getting a blue ball })=\frac{30}{70}=\frac{3}{7}$
