The probability of selection 2 black cups one after another one without replacement is 1/91
<h3>What is the probability of selection 2 black cups one after another one without replacement?</h3>
The given parameters are:
Green = 4
Blue = 8
Black = 2
Given that the selection is without replacement, this means that the number of cups reduces when one is selected
So, we have:
P(2 Black cups) = P(Black) * P(Black)
This gives
P(2 Black cups) = 2/(4 + 8 + 2) * (2 - 1)/(4 + 8 + 2 - 1)
Evaluate
P(2 Black cups) = 2/14 * 1/13
This gives
P(2 Black cups) = 1/91
Hence, the probability of selection 2 black cups one after another one without replacement is 1/91

Step-by-step explanation:
We know to find the area of a rectangle we need to multiply the length times the height.
In other words,
We know our length is 75 and our height is 55, so lets multiply it.
So our final answer is:
4125 sq. ft

Answer:
Step-by-step explanation:
The given function is:
We have to find the value of the function at x = -5/3
In order to do this we need to replace every occurrence of x in the given function by -5/3. i.e.
Thus, the value of the function at x =-5/3 is
Answer:
00:13 mm:ss
Step-by-step explanation:
There are 60 seconds in a minute. This fact can be used to convert the time period(s) to minutes and seconds either before or after you do the subtraction.
<h3>Difference</h3>
It is often convenient to do arithmetic with all of the numbers having the same units. Here, we are given two values in seconds and asked for their difference.
100 s - 87 s = (100 -87) s = 13 s
The difference between the two time periods is 0 minutes and 13 seconds.
<h3>Conversion</h3>
If you like, the numbers can be converted to minutes and seconds before the subtraction. Since there are 60 seconds in a minute, the number of minutes is found by dividing seconds by 60. The remainder is the number of seconds that will be added to the time in minutes:
87 seconds = ⌊87/60⌋ minutes + (87 mod 60) seconds
= 1 minute 27 seconds
100 seconds = ⌊100/60⌋ minutes + (100 mod 60) seconds
= 1 minute 40 seconds
Then the difference is found in the same way we would find a difference involving different variables. (A unit can be treated as though it were a variable.)
(1 min 40 s) -(1 min 27 s) = (1 -1 min) + (40-27 s) = 0 min 13 s
The difference between the two time periods is 0 minutes and 13 seconds.
