The probability is 0.035 that a male will be color-blind. What is the probability that at least one out of a group of 57 males will be color-blind?

Step 1 ：The probability that at least one out of a group of 57 males will be color-blind is equivalent to 1 minus the probability that none of the 57 males will be color-blind.

Step 2 ：The probability that a male is not color-blind is calculated as 1 - 0.035, which equals 0.965.

Step 3 ：The probability that all 57 males are not color-blind is calculated as \((0.965)^{57}\), which equals approximately 0.131.

Step 4 ：Therefore, the probability that at least one male is color-blind is calculated as 1 - 0.131, which equals approximately 0.869.

Step 5 ：Final Answer: The probability that at least one out of a group of 57 males will be color-blind is approximately \(\boxed{0.869}\).
