Answer:
0.2051
Step-by-step explanation:
The probability of follppping a coin 10 tones and getting a tail 6 times can be solved in different ways :
One way is to use the binomial probability relation :
Where :
P(x = x) = nCx * p^x * q^(n-x)
Number of trials, n = 10
p = 1/2 (probability of obtaining a tail per flip)
q = 1- 1/2 = 1/2
x = 6
P(x = 6) = 10C6 * 0.5^6 * 0.5^4
P(x = 6) = 0.205078125
P(x = 6) = 0.2051
