The mass of sodium chloride required for 1. 8 × 10^3 people is 3. 6 × 10^5 grams. Option A is the correct answer.
<h3>How do you calculate the mass of sodium chloride required?</h3>Given that weigh of the person is 50 KG. The mass of the sodium chloride in one person is given below.
The mass of sodium chloride is calculated as given below.
Hence we can conclude that the mass of sodium chloride required for 1. 8 × 10^3 people is 3. 6 × 10^5 grams. Option A is the correct answer.

Answer:
Step by step explanation:
1.1.1 We know that 1kg is equivalent to 1000g, then we can convert:
1.1.2 For 400g of tomatoes:
1.1.3. For 500ml of water, convert this into liters. We know that a 1ml is 0.001 lt
1.1.4. Since capacity is represented by the following expression:
We know that 1 cubic centimeter is equal to 0.001 liters.
Answer: 15/91 which is choice B
=================================================================
There are two methods to find this answer.
Method 1) We have 6 girls and 8+6 = 14 students. The probability of picking a girl is 6/14 = 3/7. After the first girl is chosen, we have 5 girls left out of 14-1 = 13 students overall. The probability of picking another girl (assuming the first selection was a girl) is 5/13. Multiply these probabilities: (3/7)*(5/13) = (3*5)/(7*13) = 15/91
--------------------
Method 2) We can use the nCr combination formula. Order does not matter.
We have nCr = 6 C 2 = 15 ways to pick 2 girls. See the attached image below for the steps (figure 1)
Out of nCr = 14 C 2 = 91 ways to pick 2 students. See the attached image below for the steps (figure 2)
So that's another way to get the answer 15/91.
