Answer : 7/10
Step-by-step explanation:
Given :
A bag contains 3 green and 7 white balls. Two balls are drawn from the bag in succession without replacement.
To find :
What is the probability that (i) both are white?
Finding total number of balls :-
No. of green balls = 3
No. of white balls = 7
Total no. of balls in a bag = 3 + 7 = 10.
Finding the probability of getting two white balls :-
No. of white balls = 7
Total no.of balls = 10.
Probability = 7/10.
Hence, required answer is 7/10.
