Answer:
10,141
Step-by-step explanation:
8641 + 1500 = 10,141
Since , has PMF
By definition of conditional probability,
has CDF
which is useful for immediately computing the probability in the denominator:
Meanwhile, if and , then it's always true that , so
Then
which is exactly according to the PMF.
Answer:
Step-by-step explanation:
Given, :
x P(x)
0 0.900
1 0.09
2 0.007
3 0.003
The expected variance ; Var(X) = x²*p(x) - E(X)²
The expected mean, E(X) = x*p(x)
E(X) = (0*0.9) + (1*0.09) + (2*0.007) + (2*0.003) = 0.113
Var(X) = [(0^2*0.9) + (1^2*0.09) + (2^2*0.007) + (3^2*0.003)] - 0.113^2
Var(X) = 0.145 - 0.012769
Var(X) = 0.132
Answer:
6
Step-by-step explanation:
8-2=6
A. 9
b. 12
c. 12
There are 3 thirds in 1 whole.
There are 9 thirds in 3 wholes.
If 3 is 1/3, the whole is 9.
There are 4 fourths in 1 whole.
There are 12 fourths in 3 wholes.
If 3 is 1/4, the whole is 12.
There are 3 thirds in 1 whole.
There are 12 thirds in 4 wholes.
If 4 is 1/3, the whole is 12.
