Abbey Figueroa · Answer 1

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
