<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 
Find the length of the ladder if the distance from the bottom of the ladder to the building is 9 feet.
The percentage of the time will Oliver get a written warning when he is more than 16 minutes late for his shift at work is 46.7%.
<h3>What is a density curve?</h3>
The density curve is a type or way of representation of numbered distribution data over a graph. Here, the outcomes are continues. The density curve can not be below the x-axis or horizontal line of the graph.
In a density curve,
- The mean of a density curve is indicated by μ (mu).
- The standard deviation of a density curve is indicated by Sx.
Records show that Oliver is typically 10-30 minutes late for his shift at work. The distribution for the minutes he is late forms a consistent pattern, which can be graphed as the given uniform density curve.
Oliver will get a written warning if he is more than 16 minutes late for work. The time remain after the 16 minutes is,
t=30-16
t=14 min
Thus, the percentage of the time will Oliver get a written warning is,
p=(14/30)*100
p=46.7 %
Thus, the percentage of the time will Oliver get a written warning when he is more than 16 minutes late for his shift at work is 46.7%.
