Sure! To find the probability of a swan who can swim AND does not drown, we can multiply the probabilities of these two independent events.
The probability of a swan swimming is 0.57, and the probability of a swan not drowning is the complement of the probability of drowning, which is 1 - 0.23 = 0.77.
So, the probability of a swan who can swim AND does not drown is 0.57 * 0.77 = 0.4399, or approximately 0.44.
