Answer: Our required probability is 
Step-by-step explanation:
Since we have given that
Number of coins = 3
Number of coin has 2 heads = 1
Number of fair coins = 2
Probability of getting one of the coin among 3 = 
So, Probability of getting head from fair coin = 
Probability of getting head from baised coin = 1
Using "Bayes theorem" we will find the probability that it is the two headed coin is given by

Hence, our required probability is 
No, the answer is not 
You can multiply the fractions together to get the final answer. To multiply fractions you can times the top and the bottoms of both fractions together to get the new fraction;
1/2 * 2/3 = (1*2)/(2*3) = 2/6
Then you can simplify the fraction, to do this you can find a common number between the top and the bottom fractions and then you can divide the top and the bottom by that common number. In this case the common number between the two fractions is 2;
(2/2)/(6/2) = 1/3
The answer is 1/3,
Hope this helps! :)

Answer:
(b) x -3 ≥ 0
Step-by-step explanation:
The square root function will return non-negative values, so the inequality √(x-3) ≥ 0 gives no new information. What is required is that the <em>argument</em> of the square root function be non-negative:
x -3 ≥ 0
