If the odds of winning a particular card game are 1:1, about how many times can you expect to win if you play the game eight hundred times? ( with explanation )

400

Step-by-step explanation:

A 1;1 win loss ratio means you have an equal chance of winning and losing. Therefore, you should win half of the time

800/2 = 400

400 times

Step-by-step explanation:

A 1:1 ratio means a 50 50, or half, chance. If you play 800 times, the theoretical probability of winning is 1/2 for all of those times.

800 * 1/2 = 400.

Therefore, you should expect to win 400 times if you play the game 800 times.

Hope this helps! Feel free to ask me any questions :)

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
