Option C) 125n is the expression that does not represent “increase a quantity n by 25%
<u>Step-by-step explanation:</u>
The given expressions are for the quantity n which is increased by 25%.
- Let us consider that n = 100.
- The increase of n by 25 % is equal to 125.
- Check for each options by substituting n=100 and the expression gives 125 or not.
- Check which option does not represent the condition (increase of n by 25%)
<u>Option A) n + 0.25n </u>
Put n = 100,
⇒ 100 + 0.25(100)
⇒ 100 + 25
⇒ 125
So, option A) represents the given condition.
<u>Option B) (1 + 0.25)n</u>
Put n = 100,
⇒ (1+0.25) 100
Multiply 100 with each terms inside the bracket.
⇒ 100 + 25
⇒ 125
So, option B) represents the given condition.
<u></u>
<u>Option C) 125n</u>
Put n = 100,
⇒ 125 × 100
⇒ 12500
So, option C) does not represents the given condition.
<u>Option D) 1 1/4 n</u>
Put n = 100,
Convert the mixed fraction to proper fraction
⇒ (5/4) n
⇒ (5/4) 100
⇒ 500 / 4
⇒ 125
So, option D) represents the given condition.

Step-by-step explanation:
P(at least 2 students have the same birthday)= 1- P(no 2 students have the same birthday)
Because P(A)=1-P(A'), where A is an event, and A' the complement of that event.
P(no 2 students have the same birthday)=
think of the problem as follows. We have an urn of balls, numbered from 1 to 365 (the number of the days of the year.
What is the probability of picking 56 different numbered balls, with replacements?
The first one can be any of the 365
the second any of 364 (since one selection has already been made)
the third any of the 363
.
.
and so on
the 56th selection is one of 310 left
