Answer : 2/3
2/3
2/3
For A^B to be a perfect square, B must be an even number. The probability that one die will show an even number is 1/2.
If you label the dice A and B before you throw them, the probability is 1/2.
If you choose an even number for B after you throw them, the probability is 3/4 that there will be an even number.
If you choose an odd number for B after you throw them, the probability is 1/4 that there will not be an odd number, so B must be even.
