Answer:
2/6
Step-by-step explanation:
4/12=x/6
4/12 simplified = 2/6
2/6x2= 4/12
Answer:
7/25
Step-by-step explanation:
Probability = # of favorable outcomes / # of possible outcomes
Favorable outcomes = # of blue and yellow marbles
There are 3 yellow marbles and 4 blue marbles
There are 7 blue and yellow marbles so the favorable outcome is 7
Possible outcomes = total number of marbles
12 + 3 + 6 + 4 = 25
There are a total of 25 marbles
So possible outcomes = 25
If probability= favorable outcomes / possible outcomes then the probability of pulling a blue or yellow marble is 7/25
I think 400 increased by 3.2% = 525

8 + 4= 12
Idk what you mean by which is better i guess you mean cheaper, if it is then
50x.20= 10,
35x10= 3.5 so 3.5 is less.
