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)

Answer:

480 push ups

Step-by-step explanation:

24/6 = 4

meaning they are doing 4 push ups per second, this is your slope

the equation of your line is y = 4x, you can graph this using a table of values (i attached a graph tho)

2 minutes = 120s

y = 4(120)

y = 480
