What you want is P(6∩1) or P(1∩6) or P(2∩5) or P(5∩2) or P(3∩4) or P(4∩3).
The events of rolling the dice are independent (i.e. they don't affect one another) so:
E.g.
P(6∩1) = P(6) * P(1)
P(2∩5) = P(2) * P(5)
The probability of getting a given number on a roll is 1/6 for both dice.
So:
P(6∩1) = 1/6 * 1/6 = 1/36
This is the same for any arrangement of numbers you could get from rolling two dice.
So, we can see that there are 6 arrangements of numbers that will give a sum of 7 and so that is 6 * 1/36 = 6/36 = 1/6
The answer must be
since the triangular pyramid has 4 faces and each has an area of 30
we should multiply that by 4 , so :
Answer:
HL
Step-by-step explanation:
the shared hypotenuse and congruent legs of the triangle means it is congruent by HL
you might think that SSA is also doable because there is a right angle in both triangles but it is not
a way to remember this is that "there are no donkeys in geometry" because SSA backwards is another word for donkey
C=Pi X D
Diameter is twice the radius so that would be 24 feet
C = Pi X 24
C = (22/7) X 24
C = 75.428 Feet.
-4 +or- the square root of 1 squared - 4*6*1 all over 2*4
