Answer:
1, , .
Step-by-step explanation:
probability =
Total number of persons in the party = n
a) Pr ( every person gets their phone back) = Pr (each person picks his phone ) multiplied by number of person
= × n = 1.
No of first m persons to pick = m
No of last m persons to pick = 1 - m
b) Pr (first m persons to pick each gets their phones back) =
c) Pr( first m persons get a phone belonging to last m persons) =

Answer:
The correct answer is B. 51.165
We are given two triangles,
Triangle M and Triangle S.
The scale factor of S to M is 32.
In ratio form, we can write scale factor of S to M as 32:1.
In other way 32:1 can be expressied 32:1 in fracions as 32/1.
We need to find the scale factor of triangle M to triangle S.
In order to write reverse scale factor, we just need to flip the given scale factor ratio.
Therefore, 32:1 could be flipped to 1:32.
And we could write 1:32 in fracion form as 1/32.
Therefore, scale factor from M to S is 1/32.
