The probability of getting the two balls as white is 1÷7.
Step-by-step explanation:
We have a bag containing both black and white balls.
Total number of balls in the bag =3+4 = 7 balls
Number of black balls= 4
Number of white balls= 3
To find:
The probability of getting two white balls.
Solution:
The total balls = 3+4= 7
On getting the first ball white, there will only be 2 more white balls left.
Probability of receiving the two white balls = number of white balls ÷ Total number of balls
= 3×2÷7×6 = 1÷7
Result:
Thus, the probability of getting the two balls as white is 1÷7.
