Answer:
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)
116/240 which simplifies to 29/60 by dividing 116/240 by 4/4.
Answer: I may not be correct
This is direct variation. If you move the x to the other side of the equation, it will become:
y = x
Direct variation is when y is equal to x times a constant. In this example, y is equal to 1 * x.
