Answer: 1/8

Step-by-step explanation:

When a coin is thrown 3 times , the sample space is

{HHH , HHT , HTH, HTT , THH ,THT ,TTH , TTT }

the coin lands with the heads side on all 3 flips only once out of the total sample space. That is

P( HHH) = number of times of HHH / sample space

P(HHH) = 1/8

What is the equation for 4 times the number of cows plus 2 times the number of ducks is 20

lord [1]

Let $c,d$ be the number of cows and ducks, respectively.

So, 4 times the number of cows is 4c, and 2 times the number of ducks is 2d. Together, they are $4c+2d$

This has to equal 20, so the equation is

$4x+2d=20$
