Respuesta :
1/12 because if he first picked A, that would be a 1/4 chance. If he then picked B that would have been a 1/3 chance 3x4 = 12 so 1/12
Answer:
d) 1/12
Step-by-step explanation:
There are 1 out of 4 that are chosen.
This means you do 1/4×1/3=1/12.
The probability of getting a first is 1/4.
You take a , there are 3 left now and only on B remains, so the probability or 1/3.
You multiply the two to get 1/12.
