Question

Alicia's statistics class meets 50 times during the semester and each time they meet, the probability that she will be called on to answer the first question is 1/50.Does this mean that Alicia will be called on to answer the first question exactly once during the semester? Explain

Answer 1

Explanation:

Probability she will NOT be called is 49/50

in 50 tries this becomes (49/50) to the 50th power = .3 6 4

so the likliehood she DOES get called is 1 minus this

= . 635 or 63.5 percent chance of being called during the semester
