a number is selected at random from the numbers 3,5,6,6,7,7,7,,9,9,9,9 the probability of getting an number which is an average of these numbers is?

Answer 1

1 is the avrage of these

Answer 2

Answer:

The average of the numbers is 7.

Probability= No. of possible outcomes/ Total number of outcomes

Here, No. of possible outcomes i.e,7 is 3(as 7 has appeared thrice)

Total number of outcomes is 10

Therefore the probability that the selected number is their average is 3/10= 30%
