Abox is filled with black (b), white (w), red (r), green (g), and pink (p) phone cases. a phone case is selected at random. what is the sample space for this experiment? s = {b, w, r} s = {b, w, r, g, p} s = {g, p} s = {b, r, g, p} twenty-four students took a test. fourteen students earned an a and 10 students earned a b. a student will be randomly chosen. what is the probability that the student earned an a on the last test? enter your answer as a fraction, in simplest form, in the box.

ANSWER 1 :

Sample Space ( S )= {B, W, R, G, P}     Option (ii)

Explanation:

There are five types of phone cases. Colors of the phone cases are Black, White, Red, Green, Pink.

One phone case is selecte as random, in this case we have 5 choices to select one phone case at a time.

So, Sample space is S = {B, W, R, G, P}     Option(ii)

Final answer.

Answer 2 :

Probability for student earn grade A =

Explanation :

There are total 24 students in a class.

All student appeared in a test.

14 students are got grade A

and 10 students are got grade B.

One student choose at random whose grade is A.

Probability for selected grade A student  = (total students of grade A)/(Total number of student in a class)

Probability for selected grade A student  =
