Asurvey of 120 college students is conducted and the results displayed below show that 90 students have a smartphone, 45 have a tablet, and 10 have neither. fill in the empty table cells in the two-way frequency table.

smartphone no smartphone total

tablet 45

no tablet 10

total 90 120

what is the probability (rounded to the nearest whole percent) that a randomly selected college student has a tablet but not a smartphone?

a.) 20%

b.) 5%

c.) 17%

d.) 67%

C) 17%

Step-by-step explanation:

Table:          has tablet | no tablet | total

has phone |      25              65         90

no phone   |       20            10           30

total            |       45             75         120

No tablet total: 120 - 45 = 75

No phone total: 120 - 90 = 30

No tablet phone: 75 - 10 = 65

No phone tablet: 30 - 10 = 20

Both: 45 - 20 = 90 - 65 = 25

So out of 120 students, 20 of them will have a tablet but no phone. 20/120 = 1/6 = 0.16666... ≈ 17%

answer: are you

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
