IceJOKER [234]

Answer:

(a)

\left|\begin{array}{c|c|c}---&---&---\\x&\$0&\$3\\---&---&---\\P(x)&\dfrac13&\dfrac23\\---&---&---\\\end{array}\right|

(b)$2

Step-by-step explanation:

In the given game of rolling a die. these are the possible winnings.

  • If the number showing is even(2, 4, or 6) or 1, you win $3.
  • If the number showing is either 3 or 5 you win $0.

There are 6 sides in the die.

P($obtaining a 1,2,4 or 6)=\dfrac46=\dfrac23\\P($obtaining a 3 or 5)=\dfrac26=\dfrac13

(i)The probability distribution of x.

Let x be the amount won

Therefore:

Probability distribution of x.

\left|\begin{array}{c|c|c}---&---&---\\x&\$0&\$3\\---&---&---\\P(x)&\dfrac13&\dfrac23\\---&---&---\\\end{array}\right|

(ii) Expected amount of dollar won

Expected Amount

=\sum x_iP(x_i)\\=(0*\dfrac13)+(3*\dfrac23)\\=\$2\\

You would expect to win $2.
