Question

Juan is spinning a wheel with 4 unequal spaces marked with values of $200, $300, $400, and $600. The probability of landing on $200 is . The probability of landing on $300 is . The probability of landing on $400 is . The probability of landing on $600 is . The expected value of spinning the wheel once is $1673331,500, and the expected value of spinning the wheel three times is $5001,0004,500.

Answer 1

Answer:

333 and 1000

Step-by-step explanation:

a]

The expected value of spinning the wheel is given by:

E(x)=2/9(200)+4/9(300)+2/9(400)+1/9(600)

E(x)=44 4/9+133 1/3+88 8/9+66 2/3

E(x)=333 1/3

b] The expected value of spinning the wheel thrice will be:

(expected value of spinning once)*(number of spins)

=333 1/3*3

=1000/3*3

=1000
