Sample space of two fair fifty sided dice = 50^2 = 2500
Probability of rolling a double = 50/2500 = 1/50
Probability of not rolling a double = 1 - 1/50 = 49/50
Answer:
Step-by-step explanation:
since the data is already arranged in ascending to descending u don't have to change.
upper quartile (Q3) = 3(n + 1)/4 (n means no of data)
=3(10 + 1)/4
=3*11/4
=33/4
=8.25
=8 th term + 0.25(9 th term - 8 th term)
=11 + 0.25(13 - 11)
=11 + 0.25*2
=11 + 0.5
=11.5
You have ti distribute the 5n into the brackets.
so then youll have 15n^2 + 40n.
There is no attachment so we don’t know what this angle is.
