Step-by-step explanation:
- To find the E(X) expected value, you come up with the different probabilities for each outcome
- your set of outcomes after 3 tosses would be = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT} where H is heads and T is tails
- Each element has a probability of 1/8 so let x represent number of tails
- The E(x)=Summation (x times P(x))
- Now which probability is 1.5 tails? None, so it is either 2 tails or 1 tails
- So you can expect to lose money in 1 game
- But as you play more games the probability of getting 3 tails becomes more and more likely, so you can expect to win in a 100 games
Answer:
please where is the drawing I mean the graph
Answer:
Step-by-step explanation:
We can see two pairs with same x- or y- coordinates. It means this is a rectangle.
<u>It has sides:</u>
- 12 - 6 = 6 units and
- 3 - 1 = 2 units
<u>The area is:</u>
The product (-3) * (1, 4) is (-3, -12)
<h3>How to multiply the numbers?</h3>
The expression is given as:
(-3) * (1, 4)
Rewrite the expression as
(-3 * 1, -3 * 4)
Evaluate the product
(-3, -12)
Hence, the product (-3) * (1, 4) is (-3, -12)

Answer:
each sold 60 tickets
Step-by-step explanation:
Apparently, you're supposed to set the expressions equal and solve for t; then find the values of the expressions.
60(t -1) = 20(t +1)
60t -60 = 20t +20 . . . . . eliminate parentheses
40t = 80 . . . . . . . . . . . . . . add 60 -20t
t = 2 . . . . . . . . . . . . . . . . . . divide by 40
__
60(2 - 1) = 60 . . . . . solve for Falcons sales
20(2 + 1) = 60 . . . . .solve for Eagles sales (should be equal; it is)
Each team sold 60 tickets.
