b. .857
c. .875
d. .9
How do i find that?
If the outcome of one event affects the probability of the outcome of a second event, this is termed Probability
a. predetermined
b. serial
c. independent
d. dependent
On a game show contestants randomly spin a wheel that has 40 different sections. On exactly one of these sections, there is a sad face. If the wheel lands on the sad face, the contesteant who spun it immediately loses the game what is the probability, expressed as a decimal, that a contestant will lose the game on any one spin?
a. .025
b. .1
c. .25
d. .4
a. .75

-
P(first ball is white) = 7/8
P(second ball is white) = 6/7
P(both white) = (7/8) x (6/7) = 3/4
Dependent.
1/40 = 0.025
P(second ball is white) = 6/7
P(both white) = (7/8) x (6/7) = 3/4
Dependent.
1/40 = 0.025
