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.

Students are given 3 minutes to complete each multiple-choice question on a test and 8 minutes for each free-response question.

SpyIntel [72]

Let

x------> the number of multiple choice question

y------> the number of free response question

we know that

$3x+8y=55$ -----> equation A

$x+y=15$

$x=15-y$ -----> equation B

Substitute equation B in equation A

$3[15-y]+8y=55$

$45-3y+8y=55$

$5y=55-45$

$5y=10$

$y=2$

Find the value of x

$x=15-y$

$x=15-2=13$

therefore

<u>the answer is</u>

the number of multiple choice question are $13$

the number of free response question are $2$
