Answer 1

Correct Question:

A number is selected at random from the numbers 3, 5, 5, 7,7,7,9,

9,9, 9. Then the probability that the selected number is their average.

Solution:

Step 1 : We have to find the average numbers.

Average of the Given Numbers

$\implies\sf{ \frac{3 + 5 + 5 + 7 + 7 + 7 + 9 + 9 + 9 + 9}{10} = 7 }$

Step 2: Now we have to find the probability which is required for the final answer

So,

$\implies\sf{required \: probablility \: = p \: (getting7) = \frac{3}{10} }$

Answer 2

Answer:

Hello mate ✌️

Step-by-step explanation:

Step 1 : We have to find the average numbers.

Average of the Given Numbers

\implies\sf{ \frac{3 + 5 + 5 + 7 + 7 + 7 + 9 + 9 + 9 + 9}{10} = 7 }

Step 2: Now we have to find the probability which is required for the final answer

So,

\implies\sf{required \: probablility \: = p \: (getting7) = \frac{3}{10} }
