"The sum of 5
and the twice a
number is at
most 27"
In number

5 + 2x ≤ 27

Step-by-step explanation:

I think you are asking about something like this:

5 + 2x ≤ 27

The sum of 5

5 +

and twice a

number

2x

is at

most 27

≤

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%
