Answer:
The probability of four girls is:
Step-by-step explanation:
The sample space for 4 children consist of 16 entries and is given by:
{bbbb,bbbg,bbgb,bgbb,gbbb,bbgg,bgbg,ggbb,gbbg,gggg,gggb,ggbg,gbgg,bggg,gbgb,bggb}
i.e. The total number of outcomes=16.
Now the number of outcomes of getting four girls or we can say no boys=1=Number of favourable outcomes {i.e. the outcome is gggg}
Hence,
The probability of getting four girls= (Number of favourable outcomes)/(Total number of outcomes)=1/16
Hence, the probability of four girls is:
