Answer:  =\frac{-1}{16}

Step-by-step explanation:

given data:

number to be chosen from = 1,2,3,4.

<u><em>Solution:</em></u>

ways the number can show

2*3*1=6 ways for your number to appear once.

1*1=1 ways for your number to appear twice.

3*3=9 ways for your number not to appear at all

= \frac{6(1) + 1(2) - 9(1)}{16}

= \frac{6+2-9}{16}

=\frac{-1}{16}

expected return of the player is =\frac{-1}{16}

The admission to a local fair is $10 for each adult and $6 for each child. Each ride costs $1.50 for an adult and $1 for a child
S_A_V [24]
So first start out by writing an expression for the cost of the child and the adult separately.

Child:
6 + 1r   ($6 + $1 per ride)

Adult:
10 + 1.5r   ($10 + $1.50 per ride)

to find how much more the adult will spend, just do Adult Expression - Child Expression which will be:

10 + 1.5r - (6 + 1r)  just simplify this

For Part B, use your equation from part A where r = 7
