Using the binomial probability concept ; the probability of obtaining 10 or more heads is 0.0457
Recall :
P(x = x) = nCx * p^x * q^(n-x)
Where :
- n = number of trials = 12
- x ≥ 10
- p = probability of success = 0.5
- q = 1 - q = 0.5
P(x ≥ 10) = P(x = 10) + P(x = 11) + P(x = 12)
Using a binomial probability calculator :
P(x = 10) =
P(x = 11) =
P(x = 12) =
P(x ≥ 10) = 0.01611 + 0.02930 + 0.000244
P(x ≥ 10) = 0.045654
Therefore, probability of getting <em>as</em><em> </em><em>extreme</em><em> </em><em>or</em><em> </em><em>more</em><em> </em><em>extreme</em><em> </em><em>than</em><em> </em><em>10</em><em> </em><em>heads</em><em> </em><em>is</em><em> </em>0.0457.
