4. Consider a binomial random variable with n = 5 and p = 0.7. Let x be the number of successes in the sample. Evaluate the probability. (Round your answer to three decimal places.) 5. Let x be a binomial random variable with n = 8, p = 0.2. Find the following value. 6. Let x be a binomial random variable with n = 8, p = 0.3. Find the following value. (Round your answer to three decimal places.)

Let X be a binomial random variable with p 0.3 and n 10. Calculate the following probabilities from the binomial probability mass function. Round your answers to four decimal places (e.g. 98.7654). P(X> 8)
Let X represent a binomial random variable with n = 125 and p = 0.19. Find the following probabilities. (Do not round intermediate calculations. Round your final answers to 4 decimal places.) a. P(X ≤ 25) b. P(X = 15) c. P(X > 35) d. P(X ≥ 30)
Let X represent a binomial random variable with n = 110 and p = 0.19. Find the following probabilities. (Do not round intermediate calculations. Round your final answers to 4 decimal places.) a. P(X ≤ 20) b. P(X = 10) c. P(X > 30) d. P(X ≥ 25)
Let X be a binomial random variable with n = 150 and p = 0.4. Use the normal approximation to find the following. Do not solve this as a binomial distribution problem. You must set up and use the normal approximation to receive credit. Express the final answer using 4 decimal places. a) P(48 ≤ X ≤ 66) b) P(X > 69)

Let X be a binomial random variable with p four decimal places (e.g. 98.7654) 0.7 and n 10. Calculate the following probabilities from the binomial probability mass function. Round your answers to Px-40.0352 P3 X 5)- 0.0435 Statistical Tables and Chart
(Use computer) Let X represent a binomial random variable with n = 180 and p = 0.23. Find the following probabilities. (Round your final answers to 4 decimal places.) a. P(X ≤ 45) b. P(X = 35) c. P(X > 55) d. P(X ≥ 50)
A. Let X be a binomial random variable with n = 74 and p = .6. Use the normal approximation to the binomial to find: (i) P(X ≤ 50) (iii) P(40 ≤ X ≤ 50) (v) P(X = 43) (ii) P(X ≥ 40) (iv) P(42 ≤ X < 49) B. Each time a roulette wheel is spun, there are 38 possible outcomes, 18 red, 18 black, and two green. Suppose that you ALWAYS bet "black". (i) Suppose the roulette wheel...
