Answer: 
Step-by-step explanation:

Two sets (or three technically)
sets {2, 4, 6, 8, 10} & {8,9,10}
The probability of one of the above numbers because it is a union of those two vars/sets so numbers from either set go
{2, 4, 6, 8, 9, 10}
Thats 6 of the 10 numbers
6/10
.6
If i'm wrong, sorry, haven't done this kind of stuff in a while
Answer:
$92.60
Step-by-step explanation:
7($5.99) + 7($6.49)=$41.93
$41.93 + $45.43 = $87.36
$87.36 + ($87.36 × 6%=0.06)
$87.36 + (0.06 × $87.36=5.24)
$87.36 + $5.24= $92.60
Answer/Step-by-step explanation:
Let x = 4 (you and 3 friends)
Ticket cost per head = $5.50
Drink cost per head = $2.50
Popcorn cost per head = $4.00
<em>Expression representing total amount of money spent = $5.50(x) + $2.50(x) + $4.00(x)</em>
<em />
Evaluate the expression by plugging in the value of x = 4
Total amount of money spent = $5.50(4) + $2.50(4) + $4.00(4)
= $22 + $10 + $16 = $48
<em>Total amount of money spent = $48</em>
