Job Recruitment Website - Job seeking and recruitment - The probability of A’s successful recruitment is t, and the probability of B’s successful recruitment is 1-t
The probability of A’s successful recruitment is t, and the probability of B’s successful recruitment is 1-t
The probability that B succeeds and C fails is
t/2×(1-t/2)
The probability that C succeeds and B fails is also
t/2×(1-t/2)
Therefore, the probability that only one of B and C will succeed is
2×t/ 2×(1-t/2)
The probability that one and only one of B and C will apply successfully is equal to the probability of A successfully applying,
So, 2×t/2×( 1-t/2)=1/2
