Hello!
You have to add how many trials he did
41 + 19 + 28 + 12 = 100
Now you look for the box that has 6 and tails
It has a 12 in it
You do 12/100
This can be reduced to 3/25
The answer is A
Hope this helps!
Answer:
10%
Step-by-step explanation:
24 R + 16 Blu + 10 Y + 22 G + 8 Bla = 80 total
Then you cant set up a proportion:
In order for 80 to become 100, you must multiply it by 1.25. That means in order to get X, the probability of pulling a black marble, you can multiple 8 x 1.25
8 x 1.25 = 10
Answer:
Step-by-step explanation:
you have to add the 2 to both sides
so once you do that you have -6 plus 2
you add that together and get -4
therefore x=-4
