Answer:
225 rs
Step-by-step explanation:
cost of 1 pen = 20 rs
total cost of 4 pens = 20×4= 80 rs
cost of 1 pencil = 5 rs
total cost of 5 pencils = 5×5 = 25 rs
cost of 1 box = 60 rs
total cost of 2 boxes = 60×2 = 120 rs
Total= 80+25+120 = 225 rs
If an event occurs 0 times (out of 4, in this case) then it does not occur at least once. So we can find the probability of it not occurring and then subtract that value from 1.
So, what are the chances of it not occurring in 1 trip?
1−.37=.63
What about not occurring in 2 trips?
(1−.37)⋅(1−.37)=.63⋅.63=.3969
Now what about not occurring in 4 trips?
.63^4 = 0.15752961
We must subtract this value from 1
(recall that what we just calculated is the probability of it not occurring, so the probability of it occurring at least once is:
1−0.15752961 = .84247039
TLDR - In 4 trips the chance of a guest catching a cutthroat once in under 4 trips in 0.84.
Answer:
The length of side is 42.4 inches.
Step-by-step explanation:
Given that:
Diagonal of square = 60 inches
As all sides of a square are equal, thus
Side of square = x
The diagonal will be the hypotenuse of a right angled triangle.
Using Pythagorean theorem;
Taking square root on both sides
Hence,
The length of side is 42.4 inches.
