Answer:

95 students

Step-by-step explanation:

25 students -- 19 have sibling

1 student -- (19/25)

125 students -- (19/25) * 125 = 95

Therefore, 95 students out of 125 are expected to have at least one sibling.

Thenks and mark me brainliest :))

Answer:

95

Step-by-step explanation:

Calculate the experimental probability of choosing a student who has at least one sibling: It is 19/25, or 0.56.

If 125 students are selected, this probability applies. Multiply 125 by 0.56:

0.56(125 students) = 95

95 students could be expected to report having at least one sibling.
