The probability of obtaining oranges at a local market is and that of mangoes is . Find the probability that a student will obtain oranges and not mango in the market?

3/20

Step-by-step explanation:

let P(A)=P(Oranges)

P(B)=P(mangoes)

P(not B)=1-2/5=3/5

P(A not B)=1/4×3/5=3/20

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.
