Please helpppp??!!!??

Answer 1

In order to score 2 or lower, students must score either 1 or 2.

These two events happen with probabilities 0.12 and 0.34, respectively, which means with probability
`0.12+0.34 = 0.46` a student will score 2 or less.

You may read this as "46% of students score 2 or less"

So, out of 1000 students, we expect

`1000 \cdot (46)/(100) = 460`

students to score 2 or less.
