Answer:
what are the options
Step-by-step explanation:
Answer:
0.00390625
Step-by-step explanation:
For coins :
Number of rolls, trials, n = 4
P(heads) = 0.5
Using binomial probability formula :
P(x =x) : nCr * p^x q ;
P(obtaining exactly 4 heads) = 4C4 * 0.5^4 * 0.5^0 = 1 * 0. 0625 * 1 = 0.0625
P(even number from 4 coin tosses)
Even faces = (2,4,6)
Total faces = (1,2,3,4,5,6)
P(success) = 3/6 = 0.5
P(obtaining exactly 4 even) = 4C4 * 0.5^4 * 0.5^0 = 1 * 0. 0625 * 1 = 0.0625
Hence, obtaining 4 even outcomes and 4 heads = 0.0625 * 0.0625 =0.00390625
Answer:
(81 pi)/4 or approximately = 63.62 ft^2
Step-by-step explanation:
As it is a circle, the area for a circle is pi*radius^2, where the radius is 4.5 ft, so area = 4.5^2 * pi.
Factor the quadratic equation (3x-4)(x+3). Then set the factors equal to zero.
3x-4=0, solve to get 4/3
x+3=0 x=-3
