Math Problem Statement

Let X represent a binomial random variable with n = 180 and p = 0.23. Find the following probabilities. (Do not round intermediate calculations. Round your final answers to 4 decimal places.)

Solution

To find probabilities for a binomial random variable XX, where XBinomial(n=180,p=0.23)X \sim \text{Binomial}(n = 180, p = 0.23), we can use the binomial probability formula:

P(X=k)=(nk)pk(1p)nkP(X = k) = \binom{n}{k} p^k (1-p)^{n-k}

Where:

  • n=180n = 180 is the number of trials,
  • p=0.23p = 0.23 is the probability of success on a single trial,
  • kk is the number of successes,
  • (nk)\binom{n}{k} is the binomial coefficient, calculated as n!k!(nk)!\frac{n!}{k!(n-k)!}.

Please specify the exact probabilities you need (e.g., P(X=k)P(X = k), P(Xk)P(X \leq k), P(Xk)P(X \geq k), etc.), and I'll calculate those for you!

Let me know if you want to go ahead with a specific calculation or need help with particular values.
