- Spin a wheel for $2. You will win $1 twenty-five
percent of the time. You will win $3 forty-five percent
of the time. You will win $5 the rest of the
time. Find the expected value.
- Find P(A/B) … the probablility of A given B … using the two way
table.
A X. Z
B 10 20 30
R 40 50 60
2b. Are A and B
independent? Why?
Are A and B mutually
exclusive? Why?
- You know that 60% of your chips are orange. In bag
A, the percentage of orange chips is 57% while in bag B, the
percentage is 64%. Let R = The chip is orange. Let A =
you got the chip from bag A. Let B = you got the chip
from bag B.
Find P ( R/B )
- P( A ) = .3. P( B ) - .2. P( A/B ) =
.5. Find P ( A or B ).
- Find P ( X > 3 ) given the distribution for X.
X P(
