I believe the answer is 0.24
Answer:
let sum of money be x
amount=rupees5454
rate=8%
time=30 months
convert month into year
30/12=5/2 years
Step-by-step explanation:
interest=p*t*r/100
=x*5*8/100*2
=40x/200
=x/5
so to find principal use formula
amount=principal +interest
5454=x+x/5
5454=5x+x/5
5454*5=6x
27270/6=x
4545=x
therefore ,sum of money(principal)=rupees.4545
Hope this helps u!!
Answer: 
Step-by-step explanation:
Binomial probability formula :-
, where P(x) is the probability of getting success in x trials, n is the total number of trials and p is the probability of getting success in each trial.
We assume that the total number of days in a particular year are 365.
Then , the probability for each employee to have birthday on a certain day :

Given : The number of employee in the company = n
Then, the probability there is at least one day in a year when nobody has a birthday is given by :-

Hence, the probability there is at least one day in a year when nobody has a birthday =
Tan E = 6/8 = 3/4
answer
3/4
Remember them is the best way to go.
draw the exact value triangles if you're unsure, but importantly, you just need to memorise these exact values.
