On a statistics exam, 8 students received an A, 4 students received a B, and 6 students received a C. If a single student is picked at random, what is the probability that they received an A or C?

Provide the final answer as a fraction.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

If a single student is picked at random, what is the probability that they received an A or C?

Desired outcomes

Student got an A or C

8 students received an A

6 students received a C

14 total outcomes

Total outcomes

8 students received an A

4 students received a B

6 students received a C

18 total outcomes.

The probability is 14/18 = 7/9.

the probability that a bird is green (.30) is true

step-by-step explanation:

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
