The probability with replacement is 0.6.
We have given that Susan has a jar of jellybeans. She has 10 yellow, 5 green, 3 red, and 2 black jellybeans.
We have to find the probability that she will get a yellow jellybean on her first grab, replace it, and then grab a black jellybean on her second
grab
[tex]P=\frac{number of favorable outcome }{total number of outcomes}[/tex]
Total number of jellybeans are
10 yellow+5 green +3 red+2 black=20 jellybeans
For yellow jellybeans
The number of ways =10/20
Replace it into the grab therefore again the total number of are jellybeans are 20
So,we have to find the probability for black jellybeans
There are 2 black out of 20 we have to find to getting black therefore the probability is 2/10.
Therefore probability for yellow and black jellybeans is,
10/20+2/20=12/20=6/10=3/5=0.6
