P (n) = 0.5

Step-by-step explanation:

For two events which are independent, we use the multiplication rule which states P (A and B) = P (A) * P (B). Substitute P (m) = 0.4 and P (m and n) = 0.2 into this formula.

P (m and n) = P (m) * P (n)

0.2 = 0.4*P (n)

Divide by 0.4 on both sides.

0.2 / 0.4 = P (n)

0.5 = P (n)
