Answer 1

@brittany12345678910 Suppose I spin the spinner once, what is the probability of getting a yellow?

Answer 2

2/10 i suppose

Answer 3

why do you say so?

Answer 4

its an even number out of ten well, im not sure.

Answer 5

Let's understand, if you have a coin, what's the probability of getting head?

Answer 6

1/2 50%

Answer 7

that's right. So we see probability=
\[\frac{\text{no. of favorable cases}}{\text{no. of total cases}}\]
here for the coin toss
\[\frac{1}{2}\]
Right?
