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.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

step-by-step explanation:

the correct answers i think are b. and d.

give me brainliest if it is correct!
