QUESTION 1 Consider a random variable with a binomial distribution, with 35 trials and probability of success equals to 0.5.

Answer 1

Answer #1

1) n = 35

p = 0.5

Expected value = n * p = 35 * 0.5 = 17.5

2) n = 10

p = 0.54

P(X = 4) = 10C4 * 0.54⁴ * (1 - 0.54)^10-4 = 0.169

3) n = 10

p = 0.56

P(X = 4) = 10C4 * 0.56⁴ *(1 - 0.56)^10-4 = 0.150

4) n = 10

p = 0.33

P(X = 4) = 10C4 * 0.33⁴ * (1 - 0.33)^10-4 = 0.225
