Multiply the two individual probabilities together to get 0.1804 as the probability that both will occur.

Explanation:

If (and only if) these events are independent (the outcome of one does not effect the outcome of the other), then the probability of both occurring is just the product of their individual probabilities.

#P(Q and R) = P(Q)*P(R) = (0.41)*(0.44) = 0.1804#
