Step-by-step explanation:
Possible outcomes when dice are rolled : 1 ,2 ,3,4,5 ,6
Even= 2,4,6
Odd = 1 ,3 , 5
Probability of getting even =
Probability of getting odd = 
4 dices are rolled together
a)P(3 even and 1 odd numbers)
P(3 even and 1 odd numbers)=
P(3 even and 1 odd numbers)=
b)P(2 even and 2 odd numbers)
P(2 even and 2 odd numbers)=
P(3 even and 1 odd numbers)=
=0.375
Answer:
11 2/3 pounds.
Step-by-step explanation:
Let x pounds be the amount in pounds of Brazilian coffee.
x + 27 is the amount of coffee in lbs after the mixing.
So ,working in values of dollars, we have:
6x + 4*27 = 4.5(x + 27)
6x + 104 = 4.5x + 121.5
1.5x = 121.5 - 104 = 17.5
x = 17.5/1.5 = 11 2/3 pounds answer
Step-by-step explanation:
The sum of the interior angles of a convex regular polygon is 180 times (n-2), where n is the number of sides. Since we already know the sum, we can write 3,960 = 180(n-2). If you solve for n in this equation, you will have the number of sides.
