A box has 3 red marbles, 5 white marbles and 2 blue marbles. Without looking, you draw a marble from the box and return it to the bag before selecting a second marble. What is the probability of selecting a blue marble on this first attempt and a red marble on the second attempt?

2/10 for the probability of the blue marble (20%) The probability of picking out a red marble is 5/10 (50%)

3+5+2=10 a blue marble would be 2/10=20% next a red marble would 3/9=33% chance
ReplyDeleteBre

The probability of picking a blue marble would be 2/10-20%
ReplyDeleteThe red marble would be 3/9-33%
~Shimmer~ :]
there is a 2//10 chance to get a blue and a 3/10 chance to get a red.

The chance of pulling a blue on the first try is 2/10 and the chance of pulling a red on the second try is a 3/10 chance so all together it will be a 6/100 chance and the percentage would be 6 percent.

Blue marble on the first attempt will be 2/10 and on the second attempt for the red marble it would be 3/9

It will be a 20% chance to pull a blue marble the first time and a 30% chance to pull a red marble the second time
ReplyDeleteNovotny
On the second turn there is a 30% of finding a red marble (3/10) and there is a 20% of finding a blue marble (2/10) if you add them up you will get 5/10 or 50% so the probability of picking out a red and blue marble on the second turn is 50% or 5/10.

The chance that you get a blue on the first pick would be 1/5 or 20%. The probibility that you would get a red on the seccond one would be 1/3 or 33%.

ReplyDeleteRed on the second try is 3/9 or 1/5
The probability of selecting a blue marble on the first attempt is 2/10.
ReplyDeleteRed on 2nd try is 3/9

It will be a probability of the blue marble is 20%. The probability of picking a red marble is 50%
ReplyDeleteThe first answer is 2 out of 10. The second answer is 3 out of 10.

2/10=20% for the blue marble and 3/9=33% for the red marble.
ReplyDelete-Jaeger
the probability of pulling a blue would be 2/10 or 20% and the probability of pulling a red would be a white would be a 5/10 or a 50% the other 30% or 3/10 would be the red marble.

2/10
ReplyDeletetucker
The chance of picking a blue is a 2/10 and the chance of picking a red is a 3/10 so the chance of them being picked out is a 6/100 chance and the percentage would be 6%
ReplyDeleteThe chance of pulling a blue is 2/10 and the chance of pulling a red is 3/10 so together it would be 6/100 and 6%
