Answer:
5/10 or 1/2 because there is 10 marbles in total so denominator is 10 and we are pulling white marbles and there is 5 (so what ever the variable is for this case it is the white marbles that would be the numerator so 5/10)
Hope this Helps :D
Answer: white marble: you have a 5/10% chance
Black marble: you have a 5/9% chance
Step-by-step explanation:
for the white marble you have 5 out 10 because there are half and half then you have to add them all up for the total and not placing it back in the bag there are only 9 left with still 5 black ones so you have a 5 out 9 chance to get a black one
