think of it this way for both questions, if i take ten free throws and i get luck and make 8, is it fair for me to say i am just as good at free throws as someone who shot 120 free throws and made 96? both are 80%. the more shots you take, the greater the chance that your actual skill will be shown, instead of a couple lucky shots.
if you have any questions, leave them in the comments and i will try to answer them, if this helped, pls give brainliest
