Accepted Solution
A:
Step-by-step explanation:Given:
There are 10 counters.
6 of the counters are white.
Two counters are drawn one after another without replacement.
To Find:
The probability that only one of the two counters is white
Explanation:
P(Only one of the two counters is white)
= P(white) x P( not white) + P(not white) x p(white)
Solution:
P(Only one of the two counters is white) = 6/10 x 4/9 + 4/10 x 6/9
P(Only one of the two counters is white) = 4/15 + 4/15
P(Only one of the two counters is white) = 8/15
Answer: The probability is 8/15
