John is painting a picture. He has green, red, yellow, purple, orange and blue paint. He wants to use four different colors on this picture. If order does not matter, how many ways can John pick four colors for his picture, if one of them is green?
a
6
b
15
c
10
d
4

c) 10

Step-by-step explanation:

You do 5 C 3 ( because you are choosing 3 from the remaining 5).

5C3 = 5!/(3!2!) = 10

C 10

Step-by-step explanation:

He has 6 colours to choose 3 from.

One of them is green, so he just needs to choose 2 from the remaining 5.

That's,

5C2 = 10

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
