Question

A bag contains red white and black balls only if the probabality on getting a white ball is 3/10 and that of a black ball is 2/5 then find the probabality of getting a red ball

Answer 1

Answer:

The answer is 3/10

Step-by-step explanation:

The sum of probabilities will be 1

So add the probabilities

3/10 + 2/5 + x = 1

7/10 + x = 1

x= 1 - 7/10

x = 10 - 7/10

x = 3/10

hope this will help. comment if the answer is wrong and sorry if the answer is wrong.
