The game show contestant spins a spinner with the letters E, W, Y, l and Z on it, then either an easy or a hard question is pick
prisoha [69]

Answer:

  1/5

Step-by-step explanation:

We assume the events are independent, so the probability of the joint event is the product of the probabilities of the individual events.

  P(Y or W) = 2 letters of 5 = 2/5

  P(easy) = 1 of 2 kinds = 1/2

The product of these is ...

  P((Y or W) and (easy)) = (2/5)(1/2) = 1/5

_____

In both cases, we have to assume that each of the possible outcomes is equally likely.
