This is a Binomial Probability Distribution; n=4, p=0.6. The probability of at least 1 passed is equal to the probability of 1-none passed; so x=0. The probability of x=0 (with n=4, p=0.6) is 0.0256. So, the probability of at least 1 passed is 1-0.0256 or 0.9744.

Solution:
Given, the overall percentage of success in an exam is 60.
Therefore, the probability of passing the exam is 0.6.
We need to find the probability that at least one out of four students has passed the exam.
Using the complement rule, we can find the probability that none of the four students have passed the exam.
P(None have passed) = (0.4)^4 = 0.0256
Therefore, the probability that at least one out of four students has passed the exam is:
P(At least one has passed) = 1 - P(None have passed)
= 1 - 0.0256
= 0.9744
Hence, the correct option is (B) 0.9744.
