Find the probability of getting exactly 6 girls in 8 births.

AnnyKZ [126]

Answer:

The probability of getting exactly 6 girls in 8 births is 0.1093

Step-by-step explanation:

Given : 6 girls in 8 births.

To find : The probability of getting exactly 6 girls in 8 births.

Solution :

The probability of getting girl is $\frac{1}{2}$

The probability of getting 6 girl is $(\frac{1}{2})^6$

Since we have 6 girls,

We also need to find the probability of getting 2 boys, which is

$(\frac{1}{2})^2$

There are $^8C_6$ ways to get 6 girls in 8 births

i.e, $^8C_6=\frac{8!}{6!\times 2!}$

$^8C_6=\frac{8\times 7\times 6!}{6!\times 2\times 1}$

$^8C_6=28$

There are 28 ways to get 6 girls in 8 births.

The probability of getting exactly 6 girls in 8 births.

$=28\times (\frac{1}{2})^6\times (\frac{1}{2})^2$

$=28\times 0.015625\times 0.25$

$=0.109375$

Therefore, The probability of getting exactly 6 girls in 8 births is 0.1093
