12% and The table below shows the number of marbles of different colors in a bag: Marble Experiment Color of Marbles Number of Marbles Red 5 White 8 Black 2 Deja draws a marble from the bag randomly without looking. She then draws another marble from the bag without replacing the first one. Which expression shows the probability of drawing red marbles in both the trials? 5 over 15 multiplied by 4 over 14 5 over 15 multiplied by 4 over 15 5 over 15 added to 4 over 14 5 over 15 added to 4 over 15 @heretohelpalways

12% is correct

10. anonymous

the probability of drawing a red marble the first time is$\frac{ 5 }{ 15 }$

11. anonymous

then second time would be $\frac{ 4 }{ 14 }$

12. anonymous

you need to multiply these fractions, but not add them

There are 7 cards with a picture of a rose and 2 cards with a picture of a daisy. Alfa keeps all the cards face down on the table with the pictures hidden and mixes them up. She then turns over one card face up and finds the picture of a rose on it. She removes this card from the table and turns over another card without looking. What is the probability that the card that Alfa turns over has a rose on it? 6 over 9 6 over 8 7 over 9 7 over 8

The number of chips of different colors in Vicky's bag is shown below: 5 blue chips 11 pink chips 9 white chips Vicky takes out a chip from the bag randomly without looking. She replaces the chip and then takes out another chip from the bag. What is the probability that Vicky takes out a blue chip in both draws? 5 over 25 multiplied by 5 over 25 equals 25 over 625 5 over 25 plus 5 over 25 equals 10 over 25 5 over 25 multiplied by 4 over 24 equals 20 over 600 5 over 25 plus 4 over 24 equals 220 over 600 C?

@heretohelpalways

21. anonymous

we know that the probabilities are 5/25 and 5/25

22. anonymous

now you just need to multiply these fractions

23. muscrat123

i mean A @heretohelpalways
