Mand n are two events p(m) = 0.60, p(n) = 0.20, and p (m and n) = 0.1.

find the probability of p (m or n).

0.2

0.5

0.6

0.7

.7

Step-by-step explanation:

i just took the test :)

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
