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  =

Final answer.

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

answer: 590
