OO   OR   OG   OB

BB   BR   BG   BO

\frac{n!}{(n-r)!}

\frac{4!}{(4-2)!} =12

This number doesn't include the outcome of having the same color twice.  There are four colors meaning that their four outcomes in which the same color is spun twice.

Question number 1: 5/8 (16b+24) -1/2b<br><br> Question number 2: 3/4 (16/64 + 12a) -9a
Sophie [7]

Answer:

Problem 1. <em>(19/2)b + 15</em>

Problem 2. <em>3/16</em>

Step-by-step explanation:

Question number 1

5/8 (16b+24) -1/2b  =

= (5/8) * (16/1) * b + (5/8) * 24 - (1/2)b

= 10b + 15 - (1/2)b

= (20/2)b - (1/2)b + 15

= (19/2)b + 15

Question number 2

3/4 (16/64 + 12a) -9a =

= (3/4) * (16/64) + (3/4) * 12a - 9a

= (3 * 16)(4 * 64) + (3/4) * (12/1) * a - 9a

= (3 * 1)(4 * 4) + (3 * 12)/(4 * 1) * a - 9a

= 3/16 + (3 * 3)/(1 * 1) * a - 9a

= 3/16 + 9a - 9a

= 3/16
