<u>Given</u>:
Given that there are 10 marbles in a bag. 4 are blue, 3 are black, 2 are white and 1 is red.
The marbles are selected by not replacing the drawn ones.
We need to the probability of selected a black marble and then a white marble without replacement.
<u>Probability</u>:
Let B denote the black marble.
Let W denote the white marble.
The probability of selecting a black marble is 
The probability of selecting a white marble without replacement is 
The probability of selecting a black marble and then a white marble without replacement is given by
Substituting the values, we get;
Thus, the probability of selecting a black marble and then a white marble without replacement is 
Answer:
37/45
Step-by-step explanation:
Find the least common denominator, in this case, it would be 45
2/9 (multiply both the numerator and denominator by 5) = 10/45
3/5 (multiply both the numerator and denominator by 9) = 27/45
10/45 + 27/45 = 37/45
Answer:
$2.97 is the tax. $52.47 is the Total.
Step-by-step explanation:
49.5x6%=2.97
2.97+52.47
Answer:
negative
Step-by-step explanation:
So a positive Integer has a negative and a vice versa. Notice that if the first number was negative in a difference between numbers with different signs, the answer will be negative. if the first number was positive, the answer will be positive.
Divide the top and bottom by 3 (since it is the GCF of 3 and 9) to reduce the fraction
3/3=1
9/3=3
answer: 1/3
