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

Step-by-step explanation:
We need to find the greatest common factor
Break each number into its prime components
54 = 9*6 = 3*3*3*2
36 = 6*6 = 3*2*3*3
Find the common terms
3*3*2
18
The greatest common factor is 18
