Since the probability of the coin landing leads is 1/2, simply cube 1/2 to arrive at your answer: 1/8.
You cube 1/2 because you must land heads three times in a row and each flip is independent from other flips.
Answer:
Area of geometric figures mentioned calculated.
Step-by-step explanation:
Square Perimeter = 4 x sides of square = 20. So, each equal side of square = 20 / 4 = 5
Area of square = ( Side )^2 = ( 5 )^2 = 25
Area of triangle = 1/2 (Base) (Height) = 1/2 x 3 x 3.5 = 5.25
Answer:
2, 4, 12, 48, 240
Step-by-step explanation:
We have the recursive formula a_n = 2*(n!)
Find:
a_1 = 2* 1! = 2
a_2 = 2*(2!) = 4
a_3 = 2*(3!) = 2*6 = 12
a_4 = 2*(4!) = 2*24 = 48
a_5 = 2*(5!) = 2*5*24 = 240
