If X is a binomial random with n = 8 and p = 0.6, what is the probability that X is greater than 2?
举一反三
- If X is a binomial random with n = 8 and p = 0.6, what is the probability that X is less than or equal to 2?
- if x is a binomial random
- The function f(x) that defines the probability distribution of a continuous random variable X is a:
- 已知X~b(n,p)，且E(X)=2.4,D(X)=1.44,则 A: n=4,p=0.6 B: n=6,p=0.4 C: n=8,p=0.3 D: n=24,p=0.1
- 设X~B(n,p),且E(X)=2.4,D(X)=1.44,则 A: n=12,p=0.2 B: n=8,p=0.3 C: n=6,p=0.4 D: n=4,p=0.6
