Answer

Final Answer: The probability that two randomly selected females both survived is approximately \(\boxed{0.2696}\).

Steps

Step 1 :Given the data, we know that 243 females survived out of a total of 468 females.

Step 2 :We can calculate the probability of one female surviving as the number of females who survived divided by the total number of females. This gives us \(\frac{243}{468} = 0.5192307692307693\).

Step 3 :Since the events are independent (the survival of one female does not affect the survival of another), the probability of both females surviving is simply the square of the probability of one female surviving. This gives us \(0.5192307692307693^2 = 0.2696005917159764\).

Step 4 :Final Answer: The probability that two randomly selected females both survived is approximately \(\boxed{0.2696}\).
