Answer:
Step-by-step explanation:
The expected value is the probability of an event multiplied by the number of times the event happens. And if there is more than 1 event, the expected value is the sum of those.
There are 52 cards in a deck.
There are 12 face cards in a deck. (gain 10)
There are 4 ace in a deck. (gain 20)
Any other card is 36 of them. (lose 5)
The probability of face card is 12/52
The probability of ace is 4/52
The probability of any other card is 36/52
Thus the expected values is:
(12/52)(10) + (4/52)(20) + (36/52)(-5) = $0.38
First of all, 2400=0.6x is the equation
Now, we use cross multiplication
2400/1 = 3/5x
2400*5 = 3x
12,000 = 3x
12000/3= 4000
<u>The total fundraiser goal is $4,000.</u>
Hi! Your answer is:
