Agame is played as follows: a coin is flipped 3 times. if 3 heads come up, then you win $5. if 2 heads come up, then you lose $5. if 1 head comes up, then you lose $4. if no heads (all tails) come up, then you win $4. in two or more sentences, explain whether or not the game is fair.

Step-by-step explanation:

Given that A game is played as follows:

A coin is flipped 3 times.

If 3 heads come up, then you win $5.

If 2 heads come up, then you lose $5.

If 1 head comes up, then you lose $4.

If no heads (all tails) come up, then you win $4.

No of heads X     0    1    2     3

Prob              p    

Win                        5  -5   -4    4

Expected win of the game = Sum of win amount * Prob

=

Since expected value is not 0 the game is not fair.

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
