Question

Joel scores in 80% of his games. His team is starting the playoffs, and if they make it to the state championship, they will have played 5 games. Joel wants to determine the probability that he scores in 4 of the 5 games.

Answer 1

D

Explanation:

USING A TABLE OF RANDOM DIGITS BETWEEN 0 ANS 9. LET 0-7 REPRESENT JOEL SCORING AND 8-9 REPRESENT JOEL NOT SCORING. SELECT FIVE DIGITS

Answer 2

I feel like some information is missing here.

4 out of 5 games is 80%:

`(4)/(5) *100%=4*20%=80%`

So if we know, as a rule that "Joel scores in 80% of his games.", the probability that he will score in 80% of his games is 1 - that is, we know it for sure
