Question

there are 5 white and 7 red balls find the probability that a ball drawn at random is red​

Answer 1

Answer:

7/12

Step-by-step explanation:

red =7

white=5

total no. of balls =5+7=12

now, 7/12 is the answer

Answer 2

Answer:

7/12

Explanation:

Total no of White balls = 5

Total no of Red balls = 7

So, total no of balls = 12  

Probability of drawing a white ball = (no of outcomes of white ball) / ( total no of outcomes) = 5/12

∴ Probability of drawing Red ball = (12 - 5)/12 = 7/12

OR

Total no. of balls = 5 + 7 = 12

∴ 7/12 = is the probability that a ball drawn at random is red​
