Answer:
Step-by-step explanation:
The probability is 
P
(
A
)
=
1
3
Explanation:
To calculate the probability you have to count the number of all possible results 
|
Ω
|
and the number of results that fulfill the given condition 
|
A
|
.
In this case 
Ω
=
{
1
,
2
,
3
,
4
,
5
,
6
}
 Thereare 6 possible result of a dice toss. So 
|
Ω
|
=
6
The given condition is "the result is divisible by 
3
", so 
A
=
{
3
,
6
}
 - those are the only numbers divisible by 
3
, so 
|
A
|
=
2
.
Finally to calculate the probability we have to divide 
|
A
|
 by 
|
Ω
|
.
P
(
A
)
=
|
A
|
|
Ω
|
=
2
6
=
1
3
Note The probability is never larger than 
1
, so if you get such result then there must be a mistake in calculations.

Answer:
She purchased the item at a price of Rs 1,406.
Step-by-step explanation:
5% of discount:
This means that she paid 100% - 5% = 95% = 0.95 of the original price of x, that is, 0.95x, and 0.05x was the discount.
Original price:
She got the discount amount of Rs 74.
74 is 5% of the original price, that is:



What price she purchased:
74 subtracted from the original price, that is, x - 74. So 1480 - 74 = 1406.
She purchased the item at a price of Rs 1,406.
