Question

In Kim’s homeroom, 4 students have no siblings, 9 students have

1 sibling, 8 students have 2 siblings, and 2 students have 3 or more siblings. Is it likely that a student chosen at random will have 1 or more siblings? Explain.

Answer 1

Yes because there is an 82.6% chance of a student chosen at random having one or more siblings.

Explanation:

There are a total of 23 students of which 19 have 1 or more siblings. This means there's a 82.6% (19 is what percentage of 23) chance that a student chosen at random will have one or more siblings. Since this percentage is significantly high we can say it's likely that a student chosen at random will have 1 or more siblings.

Answer 2

(9+8+2)/(4+9+8+2)=19/23=82%
Therefore very likely
