Question

On checking the boxes of 5 litre of ghee available in a shop. the actual amount of ghee is found as follows: 4.798 kg, 4.795 kg, 4.64 kg, 4.805 kg, 4.86 kg. 4.825 kg. 4.914 kg. 4.801 kg. 4.798 kg. 4.681 kg A box of ghee is picked at random. Find the probability that the amount of ghee in the box picked is : 4,798 (6) between 4.8 kg and 4.9 kg (ii) less than 4.8 kg​

Answer 1

Answer:

between 4.8kg and 4.9 kg

Answer 2

Solution :-

→ Total number of outcomes = 4.798 kg, 4.795 kg, 4.64 kg, 4.805 kg, 4.86 kg, 4.825 kg, 4.914 kg, 4.801 kg, 4.798 kg, 4.681 kg = 10 .

now,

→ favourable outcomes of 4.798 kg = 2 .

so,

→ Required probability = favourable outcomes / Total number of outcomes = 2 / 10 = 1/5 (Ans.)

now,

→ favourable outcomes of weight between 4.8 kg and 4.9 kg = 4 .

then,

→ Required probability = 4/10 = (2/5) (Ans.)

also,

→ favourable outcomes of weight less than 4.8kg = 5 .

then,

→ Required probability = 5/10 = (1/2) (Ans.)
