Since this is not my area of expertise, I searched Google under the key words "hypertonic" to get these possible sources: https://www.google.com/search?client=safari&rls=en&q=hypertonic&ie=UTF-8&oe=UTF-8 In the future, you can find the information you desire more ...

**maths (?)**

Again you are unclear. Are you choosing from the selected cards or the remainder of the deck? If of the 7 cards removed, red card is 2/7. neither king nor queen = 5/7 I'll let you do the rest.
*February 16, 2014*

**maths**

I'm not sure what "it" refers to. As long as the choice is random, there are 15 odd cards of the 30. 15/30 = ?
*February 16, 2014*

**Statistics**

Sampling with replacement puts the chosen unit back in the pool, while without replacement does not. Probabilities remain the same with replacement, but both numerator and denominator are reduced by one in without replacement in subsequent choices.

**Math**

3s + 4j = 360 s + 3j = 220 Multiply second equation by 3, then subtract first from second. 3s + 9j = 660 5j = 300 Solve for j, then insert that value into either equation to find s.

Since half of the isosceles would a right triangle, use the Pythagorean theorem with 1/2 value of the base. 4^2 + altitude^2 = 5^2 Solve for the altitude.
