balls selected are white is
​

Answer 1

Answer:

the probability = no of fav outcomes /total outcomes = 6/6+4 = 6/10 =3/5 answer....

Answer 2

Answer:

Probability that ball chosen will be white is 0.6

Step-by-step explanation:

In this Question,

We have been given that a urn contains 6 white and 4 black balls.

`A die is rolled and that number of balls are choosen from the urn

We have to find probability that the ball selected is white

Probability that ball selected is white = $\frac{total\ number\ of\ white\ balls}{total\ number\ of\ white\ balls\ +\ total\ number\ of\ red\ balls}$

Probability = $\frac{6}{6+4}$

Probability = $\frac{6}{10}$

Probability = $\frac{3}{5}$

Hence the probability that selected ball is white is 0.6
