The sum of 2 numbers is 15 and their difference is 5

10 and 5

Step-by-step explanation:

Difference means subtraction and sum means addition, so two numbers added together is 15 but subtracted is 5 so we know that the sum is 15 and when one of the numbers subtracts the other, the difference is 5, so 5 is one of the numbers. Therefore:

15 - 5 = 10, 10 is the other number

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
