Answer:
μ = 1 The firm expects that one oil exploration will be successful.
v(x)= 0.9
Step-by-step explanation:
The first step is to define the random variable x as:
x: number of oil explorations being succesful
Then x can be take this values:
x = 0 , x =1 ... x =10
x is a binomially distributed random variable with parameters.
p = 0.1 and n=10
And the mean or the expected value of x is:
μ = E(x) = np
Then μ = 10*0.1 = 1
And the variance of x is:
V(x) = np(1-p)
V(x) = 10(0.1)(1-0.1)= 0.9
Answer:
x<1.5
explanation: move 4 to other side subtract it with 26.5 then divide it by 15
Answer: The answer is (4,5)
Step-by-step explanation:
The possibility of landing on yellow would be 8/72 times because 1/9=x/72.
9 times 8 is 72 so 8 times 1 is 8/72. 1/9 is from the 1+7+1=9. 1/9.
The answer is 8/72 or 1/9.
