Of the last three chapters tests given in a computer programming class, 11 students passed all three tests , 9 students passed two tests, and 2 students passed one test. If a single student is picked at random what is the probability that the student passed all three tests or passed one test ? Provide the final answer as a fraction

59%

Step-by-step explanation:

simply, it would be 11+2/22 = 59%

I assume there are no student that passed 0 tests

13/22

Step-by-step explanation:

The total number of students is 11+9+2=22. The number that passed all three tests or passed one test is 11+2=13, so the answer is 13/22.

1 and 2

step-by-step explanation:

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
