Answer:
The probability that Joe's stock will go up and he will win in the lottery is 0.00005.
Step-by-step explanation:
Let the events be denoted as:
<em>X</em> = the stock goes up
<em>Y</em> = Joe wins the lottery
Given:
P (X) = 0.50
P (Y) = 0.0001
The events of the stock going up is not dependent on the the event of Joe winning the lottery.
So the events <em>X</em> and <em>Y</em> are independent of each other.
Independent events are those events that can occur together at the same time.
The joint probability of two independent events <em>A</em> and <em>B </em>is,
Compute the value of P (<em>X ∩ Y</em>) as follows:
Thus, the probability that Joe's stock will go up and he will win in the lottery is 0.00005.

Answer:
x = 36
Step-by-step explanation:
The parallel lines divide the transversals proportionally, so ...
x/60 = 24/40
x = 60(24/40) = 60(3/5)
x = 36
There are 8 possible outcomes with corresponding winnings:
HHH ==> 1 + 2 + 3 = 6
THH ==> -1 + 2 + 3 = 4
HTH ==> 1 - 2 + 3 = 2
HHT ==> 1 + 2 - 3 = 0
TTH ==> -1 - 2 + 3 = 0
THT ==> -1 + 2 - 3 = -2
HTT ==> 1 - 2 - 3 = -4
TTT ==> -1 - 2 - 3 = -6
Then
