A spinner is divided into five equal sections. It’s a game of chance 5 possibilities. What is the probability of $15 occurring?
What is the expected value mean?
What is the standard deviation?

X $1 $2 $5 $10 $15
P(x) .4 .3 .15 .1 ?

answer: the answer is c.

step-by-step explanation:

she’s dividing 1/3 of the flour into 2 jars.

hope this : )

if x = 1, then the answer is 3.5

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

you need to give us more information since we can't answer
