Step-by-step explanation:
5+3+2 = 10
Chance of pulling out a yellow marble = 3/10
Once you pull out the marble there are 9 marbles left, 2 yellows, 2 blacks and 5 whites.
Chance of then pulling out a black marble = 2/9
3/10 x 2/9 = 6/90
6/90 = 1/15

Answer:
<h3>
a) Mean=1.2</h3><h3>b) The standard deviation is
</h3>
Step-by-step explanation:
<h3>Given that the discrete probability distribution below :</h3><h3><u>Outcome Probability
</u></h3>
0 0.35
1 0.36
2 0.14
3 0.08
4 0.04
5 0.02
6 0.01
<h3>a) To find the mean of this distribution :</h3><h3>The formula is
</h3><h3><u>X P(X) XP(X) </u>
<u /></h3>
0 0.35 0 0
1 0.36 0.36 0.36
2 0.14 0.28 1.12
3 0.08 0.24 2.16
4 0.04 0.16 2.56
5 0.02 0.1 2.5
6 0.01 0.06 2.16

- Now substitute the value in the formula we get
<h3>Therefore Mean=1.2</h3><h3>b) To find Standard Deviation :</h3><h3>The formula is
</h3>
- Substitute the values i the formula we have
<h3>Therefore the standard deviation is
</h3>
