Zoe rolls two fair six-sided number cubes. What is the probability that at least one number cube shows a 5?
1 answer:
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

Sin2x = 2sinxcosx;
cos2x = (cosx)^2 - (sinx)^2;
tan2x = (sin2x)/(cos2x);
cosx = 5/13 from formula (sinx)^2 + (cosx)^2 = 1;
=> sin2x = 120/169;
