Answer:

2/15.

Step-by-step explanation:

The  prime numbers in the first 10 numbers are: 2, 3, 5, 7 . That is a total of 4.

Prob( first number drawn is prime) = 4/10 = 2/5.

Prob( second number drawn is prime) = 3/9 = 1/3.

Required probability  is 2/5 * 1/3

= 2/15.

Hi there!

A valley farmer has 26 employees and he pays each of them $410 per week.

After paying them for one week he has $162 dollars left. We need to find how much money he had at first.

So the first step is to multiply $410 on 26 since he gives 410 dollars to each employee, which he has 26.

$410 · 26 = $10,660

So he had $10,660 before he paid the workers, but he still had $162 left. To find out his overall total of money he had we need to add $10,660 and $162 which will be $10,822.

The farmer had $10,822

Hope this helped!~
