Question

A bag contains 3 red balls and 5 black balls. A ball is drawn at random from

the bag. What is the probability that the ball drawn is red?​

Answer 1

Step-by-step explanation:

There are 8 balls in total

Since there are 3 red balls the probability will be:

3/8

So your answer is 3/8

Hope it helps✌✌

Answer 2

Answer:

 $\frac{3}{8}$

Step-by-step explanation:

Number of red balls = 3

Number of black balls = 5

Total number = 5+3 = 8

Probability of red ball = $\frac{Red balls}{Total balls} = \frac{3}{8}$

Hence, the probability of red ball is  $\frac{3}{8}$.

HOW TO FIND?

Probability = outcomes/total number of outcomes

Example : A bag contains 7 red balls and 5 black balls. A ball is drawn at random from  the bag. What is the probability that the ball drawn is red?​

Ans. Number of red balls = 7

Number of black balls = 5

Total number = 7 + 5  = 12

Probability of red ball = $\frac{Red balls}{Total balls} = \frac{7}{12}$

Hence, the probability of red ball is $\frac{7}{12}$
