Identify the resulting probability as theoretical or experimental. one-half of the people in a chess club are adults 21 years old or older. the other half are younger. what is the probability that a club member chosen at random will be under 21 years old?
a. the experimental probability is 50%.
b. the experimental probability is 75%.
c. the theoretical probability is 75%.
d. the theoretical probability is 50%.

D. The theoretical probability is 50%.

theoretical cuz' no experiment done yet. the prob is 1-50%=50%.

so D is the ans.

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
