Answer:
27/32
Step-by-step explanation:
2x³ for x = 3/4 is ...
2(3/4)³ = 2·3³/4³ = 2·27/64 = 27/32
divide the frequency of 6 by the total frequency to obtain a probability

Answer:
D
Step-by-step explanation:
if you look at the graph you can see that if you add 2 each tie to a problem it will not go left but right because right means the value is going up and left means the value is going down
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
