Answer:
Probability of obtaining at least one five = 3/12
Step-by-step explanation:
Number cube have six faces.
Then two number cube have 12 faces total but independent 6 two faces
Number of 5 in a number cube is one.
Probability of obtaining a 5 in a number cube = 1/6
Probability of obtaining at least one five in the two number cube mean = probability of obtaining a five or two five
= 1/6 + 1/12
= 3/12
x * x = x^2
x * .7 = .7x
-6 * x = -6x
-6 * .7 = -4.2
x^2 + .7x - 6x -4.2
x^2 - 5.3 - 4.2
x = 6

w=32
32*2=64
theoretical probability
This is theoretical probability. The 7 pieces of paper each bear one number from {1, 2, ... , 6, 7}. There is only one piece of paper marked 7. So the probability of drawing a 2 is 1/7.
