Step-by-step explanation:
Hello!
You have X~Bi (n;ρ)
Where:
n=10
ρ= 0.10
For all asked probabilities you need to use a Binomial distribution table. Remember this table has the information of the cummulative probabilities P(X≤x).
a. f(0) ⇒ P(X=0) = 0.3487
b. f(2) ⇒ P(X=2) ⇒ P(X≤2) - P(X≤1) = 0.9298 - 0.7361 = 0.1937
c. P(X≤2) = 0.9298
d. P(X ≥ 1) = 1 - P(X ≤ 1) = 1 - 0.7361 = 0.2639
e. E(X)= nρ = 10*0.10 = 1
f. V(X)= nρ(1-ρ) = 10*0.1*0.9 = 0.9
σ= √V(X) = √0.9 = 0.9487
I hope it helps!
The binomial experiment depicts that f(0) will be 0.3487.
How to compute the binomial experiment
From the information given, it can be noted that:
n = 10
p = 0.10
q = 1 - 0.10 = 0.90
f(0) ⇒ P(X=0) = 0.3487
f(2) = P(X=2) ⇒ P(X≤2) - P(X≤1)
= 0.9298 - 0.7361
= 0.1937
P(X≤2) = 0.9298
P(X ≥ 1) = 1 - P(X ≤ 1)
= 1 - 0.7361 = 0.2639
E(X) = nρ
= 10 × 0.10 = 1
V(X) = nρ(1-ρ)
= 10 × 0.1 × 0.9
= 0.9
σ = √V(X) = √0.9
= 0.9487
