Question

Suppose you are playing a game with two number cubes. Let A represent rolling 2, 3, or 4, and B represent rolling 1, 5, or 6.
The probability of A is 1/2 and the probability of B is 1/2.

simplify (1/2A + 1/2B)
and
What is the probability that one number cube shows 2, 3, or 4, and the other shows 1, 5, or 6?

Answer 1

someone please help me with this one.

Answer 2

A= 3/6 = 1/2

B = 3/6 = 1/2

So,

\[(1/2)^2 + (1/2)^2 = 2/4 = 1/2\]

= 1/2

Answer 3

how do I get the answer to B?
