Question

The probability of winning a game is 40%. How many times should you expect to win if you play 40 times? (2 points)

Answer 1

\[40\times .4\]

Answer 2

\(\Large \color{purple}{\rightarrow 0.4 * 40 }\)
\(\Large \color{purple}{\rightarrow 16 }\)

You get 16 times as the answer.

Answer 3

\(\Large \color{purple}{\rightarrow 40percent = {40 \over 100} = 0.4 }\)

Answer 4

if the probability you win does not change, then the expected value is the probability you win times the number of times you play
