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.
