Answer:
The proportion is [tex]\frac{41}{100}[/tex] = 0.41 or 41%
Step-by-step explanation:
Hello!
The expected proportion is calculated as "the number the event of interest has occurred"(i.e. success) divided the total of trials.
In this case, your success is the number of times your friend guessed a card correctly in 100 trials.
The proportion is [tex]\frac{41}{100}[/tex] = 0.41 or 41%
I hope it helps!
