Theoretical probablity=desiredoutcomes/totalpossibleoutcomes
desired=number of white marbles=20
total possible=red+blue+white=30+50+20=100
so theoretical probablity=20/100=2/10=0.2=20%
I would like to have a patient and good teacher,who is not angry or stressed,or give us lots of homeworks.
Hope I helped u :)
I dont quite undeerstand but the gcf for both are..., if that helps is 4 because
30:2*2*2*2*2
22:2*2 5
3+7 = 10
You do 500/10 which is 50 to find out 1
1 = 50
3 = 50 x 3 = 150
7 = 50 x 7 = 350
The ratio is 150 : 350
<span>I believe in this item, we are asked to determine how many 5's should be added together in order to form 100. This is calculated by dividing 100 by 5. The answer by completing the operation would be equal to 20. Hence, the answer is 20. </span>
