Step-by-step explanation:
The expected value is the sum of each probability times the value.
E = 0.25 (10) + 0.75 (-5)
E = -1.25
The stock is expected to decrease by $1.25.
Answer:
$333.5
Step-by-step explanation:
First we have to find 45% of 230 and then add that value to 230
(we can also find 145% of 230, which is essentially the same thing)
so 45% of 230 is:
230*(45/100)= $103.5
230+103.5= $333.5
If Daniel has two minutes and each game lasts for 15 seconds then he has eight tries to win. ( 120 seconds divided by 15 seconds = 8) And if his odds are .1 that means he has a 10% chance each game. 10% x 8 tries = 80% chance. or .8
