Find probability
Answer to Problem 44CR
Explanation of Solution
Given information:
You randomly pick two marbles from a bag containing
Calculation:
Consider the given data,
A bag containing
Total marbles in bag
So the number of marbles for second choice is less than one, means it affect the probability of second event, first and second events are dependent.
It is formulate as,
Similarly,
The second marble is picked up without replacing the first, so the number of marbles available for second choice is
The number of possible outcomes to choose a marble out of six is six.
Out of six, three marbles are red, as one red is already chosen, without replacing.
It means the number of favorable outcomes to choose a red marble is three.
Now,
Hence,
