Given:
The results of the simulation.
Number of puppies = 4
To find:
The estimated probability that at least two of the puppies will be female.
Solution:
Let heads (H) = Female puppy.
Let tails (T) = Male puppy.
The results of the simulation are HHHH, TTTH, TTHH, HHTT, THTH, HTTH, HHHT, HHTT, HTHH, THTT.
Total outcomes = 10
The results having 2 or more H are HHHH, TTHH, HHTT, THTH, HTTH, HHHT, HHTT, HTHH.
Favorable outcomes = 8
Now,
[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
[tex]\text{Probability}=\dfrac{8}{10}[/tex]
Probability in % is
[tex]\text{Probability}\%=\dfrac{8}{10}\times 100[/tex]
[tex]\text{Probability}\%=80\%[/tex]
The estimated probability that at least two of the puppies will be female is [tex]\dfrac{8}{10}=80\%.[/tex]
Therefore, the correct option is B.
