how many blue marbles are there? how many total marbles are there?
4 blue and 4+5+3=11
yes! so, what is the probability of getting blue?
not quite! think of it this way: probability of getting blue = number of blue/number of total marbles
number blue marbles = ? number of total marbles = ? number of blue marbles/number of total marbles = ?
4 blue and 11
right! so what is the number of blue marbles/the number of total marbles?
so that my answer
oh, I'm sorry, you made a mistake earlier! how many total marbles are there? your original answer was wrong and I didn't see it what is 3 + 5 + 4? it's not 11
@Vocaloid now what 12
ok! now try the probability again how many blue marbles are there? how many total marbles are there? what is the probability of getting a blue marble?
I'm sorry, I didn't catch your mistake earlier
45+4 +3 = 12 4 blue
it will be 1/12
please try again probability of getting a blue marble = number of blue marbles/number of total marbles
please try again: 1. how many blue marbles are there? 2. how many total marbles are there? what is the number of blue marbles DIVIDED by the number of total marbles?
4 divided 11= 3
1/3 is my answer
yes! 4/12 = 1/3 you're done
