Answer:
40 N
Step-by-step explanation:
To know which bag is cheaper, you have to compare both package price as cost per kilograms of sugar. Then we can find how much we can save by finding the difference between the two values
The 500g sugar package cost is N195. Every kg is equal to 1000g, so the price will be: 195N/ (500g*1kg/1000g)= 390 N/kg
The 25kg sugar package cost is N8750. so the price will be: 8750N/25kg= 350 N/kg
The amount you save per kg if you buy 25kg package instead of 500g will be: 390 N/kg - 350N/kg = 40 N/kg
Answer:
Permutation without repetition
Step-by-step explanation:
The order of the cards matter, which makes it a permutation, but since none of the cards are exactly the same, repetition isn't allowed/possible

Answer:
2/7
Step-by-step explanation:
There are 22 (12 + 10) total students in the class. That means that the chance of the first student picked being a girl is 12/22.
Now, we must calculate the chance of the next student to be picked <em>also </em>being a girl - however, there is a trap here! Remember that since a girl has been picked, the total student pool has decreased to 21 and and the total number of girls has decreased to 11. This means the new chance of girl being picked is 11/21.
To find the probability of both these events happening in conjunction, these fractions must be multiplied. 12/22 * 11/21 = 132/462, which simplifies to 2/7.
