Marble problem and algebra.
Marbles in a bag math problem.
In the above problem the number of favorable outcomes is 4 because there are blue marbles in the bag.
Each bag contains an unknown number of marbles.
When solving probability problems remember this important formula.
Find the probability of pulling a yellow marble from a bag with 3 yellow 2 red 2 green and 1 blue i m assuming marbles.
How many marbles are in the bag.
If 100 of the marbles in the first bag are placed in the second bag the number in the second bag is increased by 50.
The total number of outcomes is 12 because there are 12 different marbles in the bag.
There are 30 blue marbles in a bag which is 40 of the marbles in the bag.
And so this is sometimes the event in question right over here is picking the yellow marble.
So they say the probability i ll just say p for probability.
There are two bags.
