    Step-by-step explanation:

    This can be easily solved if we know the formula:

    P (A or B) = P (A) + P (B) - P (A and B)

    So, for this problem, we can modify the formula to be:

    P (M or N) = P (M) + P (N) - P (M and N)

    Using given information, we can solve:

    P (M or N) = P (M) + P (N) - P (M and N)

    P (M or N) = 0.6 + 0.2 - 0.1

    P (M or N) = 0.7

    Last answer choice is right, 0.7
