So the next time.
Marbles in a bag probabilitty.
Bag a has 1 red marble and 99 blue marbles.
Further if we assume that the first marble selected was red then 3 red marbles are left in the bag.
Problems demonstrate non conditional and cond.
The chance is 2 in 5.
4 are blue and 1 is red.
2 blue and 3 red marbles are in a bag.
Thanks hello rubies.
Solution there are 5 in total 4 are blue so 4 5 or80 is it right.
If we got a red marble before then the chance of a blue marble next is 2 in 4.
4 are blue and 1 is red.
What is the probability that a blue marble gets picked.
This math education video demonstrates how to calculate the probability of removing colored marbles from a bag.
There are 5 marbles in a bag.
Marbles in a bag.
Bag b has 5 red marbles and 95 blue marbles.
P first red 1 3 after selecting the first marble 11 marbles are left in the bag.
The probability of the first marble selected being red is the same as before 1 3 since total number of marbles and number of red marbles is the same.
Say i have 2 bags with 100 marbles in each.
If we got a blue marble before then the chance of a blue marble.
There are 5 marbles in a bag.
Or is the probability equal.
