A biased coin has a probability of 0.4 of coming up heads. What is the probability that when flipped one hundred times it comes
inn [45]

Using the binomial probability relation ; the probability that an head is obtained at least 50 times is 0.0271

<u>Using the binomial probability relation</u> :

  • P(x = x) = nCx * p^x * q^(n-x)
  • p = probability of success = 0.4
  • q = 1 - p = 0.6
  • n = number of trials = 100

P(x ≥ 50) = p(x = 50) + p(x = 51) + ...+ p(x = 100)

<u>Using a binomial probability calculator</u> :

P(x ≥ 100) = 0.0271

Therefore, the probability that atleast 50 heads are obtained in the trial is 0.0271

Vinil7 [7]

Answer:

7x / 7 < 21 / 7

x < 21/7

x < 3

x = 3

Check:

7x < 21

7(3) < 21

21 = 21
