The probability is #0.36# or #36%#

Explanation:

The probability that one chosen person is off blood type #A# is #40%=0.4# so the probability that he is not of blood type #A# is #0.6#.
To calculate the probability that none of #2# people is of blood type #A# you have to multiply the probabilities:

#0.6xx0.6=0.36# or #36%#.
