Question

A box contains one blue (b), two red (r), and two yellow(y) blocks. A coin has one side with heads (h) and one side with tails (T). Alyssa will flip the coin and then choose a block from the box without looking. Answer part B also.

Answer 1

The answer to your problem is:

Part A. Box B:

H,B | H,R | H, Y

T,B | T,R | T, U

Part B. 0.2

Explanation:

Part A.

We can put it to this diagram shown:

`\left[\begin{array}{ccc} &H& \\l&l&l\\B&R&Y\end{array}\right]` “ l “ Representing what H is going to. ( Same with second )

`\left[\begin{array}{ccc} &T& \\l&l&l\\B&R&Y\end{array}\right]` “ l “ Represening what T is going to

So if we complete it, it will equal:

H,B | H,R | H, Y

T,B | T,R | T, U

Part B.

We will just solve:

`(1)/(2) * (2)/(1+2+2) = (1)/(2) * (2)/(J) = (1)/(J) = 0.2`

0.2 being our answer

Thus the answer to your problem is:

Part A. Box B:

H,B | H,R | H, Y

T,B | T,R | T, U

Part B. 0.2
