Answer:

Step-by-step explanation:
Total possibilities when we a roll a die at a time are 6
given we should have four for first time and then three
let us assume we rolled the dice we may get 1,2,3,4,5,6(any of these) the probability to get 4 is
PROBABILITY=
Favourable chances=1
Total chances=6
Probability=
the prabability to get 4 in first roll is
.
let us assume we rolled the dice for second time again we may get 1,2,3,4,5,6(any of these) the probability to get 3 is
Favourable chances=1
total chances=6
probability=
the probability to get 3 in second roll irrespective of first one is 
the probability to get 4 in first time and then 3 is
The probability to occur both events at a time is multiplication of individual probabilities
So,
probablility to get 4 in first roll=
probability to get 3 in second roll=
probability to occur both at a same time is =

=
Answer:
i know ima lil late but heres the answer
Step-by-step explanation:
Median is 7, two numbers in the middle is 8 and 6, 8+ 6 = 14 divided by 2 is 7.
Range is largest number minus the smallest number. Largest number is 13 and smallest number is 1. 13-1 equals 12. Range is 12.
12 - 7 = 5 answer is 5
Write an equation where x = Justin's orders
93 = (x) + (2x) + (x + 5)
Simplify the equation:
93 = 4x + 5
Subtract 5 from both sides:
88 = 4x
Divide 4 on both sides:
22 = x
Solve for the orders:
x = 22 = Justin
22(2) = 44 = Chang
22 + 5 = 27 = Heather.
Hope this helps!
Answer:
D is the correct answer.
Step-by-step explanation:
You would add $6.00 to $13.20, making 19.20, subtracting 4 x $1.55 (6.2) leaves you with $13, the cost of the pizza. So therefore, it would be 4d + $13.00 – $6.00 = $13.20; $1.55.
