Answer:
0
Step-by-step explanation:
given that we roll a fair die repeatedly until we see the number four appear and then we stop.
the number 4 can appear either in I throw, or II throw or .... indefinitely
So X = the no of throws can be from 1 to infinity
This is a discrete distribution countable.
Sample space= {1,2,.....}
b) Prob ( 4 never appears) = Prob (any other number appears in all throws)
= 
where n is the number of throws
As n tends to infinity, this becomes 0 because 5/6 is less than 1.
Hence this probability is approximately 0
Or definitely 4 will appear atleast once.
Simple proportions.
You want a 1:5 ratio.
You have a 5:1 ratio.
So you add another 24 drops of white.
5:25 = 1:5
or
5/x = 1/5 and cross multiply.
Answer:
A. Draw a line from the segment to any point on the fold line.
Step-by-step explanation:
When using the paper folding method to find the midpoint of a line segment we take the following steps:
- Draw a line segment on the tracing paper
- Fold the tracing paper so that the endpoints lie on top of each other
- Mark the intersection of the fold and the segment with a point
These steps include statements B, C, and D. Drawing a line from the segment to any point on the fold line, which is statement A, is not included in these steps because it is not needed.
Thus, choice A is not a step in using paper folding to find the midpoint of a line segment.
