Beth wants to know the average value of a card in a standard 52-card deck. She sets the value of aces to 1, jacks, queens, and kings to 10, and all other cards to their face value. She picks a single card from the deck, records its value, and shuffles the deck before picking again. She does 5 trials on Monday, 10 trials on Tuesday, and so on, until her final set of 25 trials on Friday. Knowing that the actual average value of a card is 6.5, what can you conclude from this table?

A) The larger the number of trials, the closer the data was to the theoretical probability.

Eliminate

B) The smaller the number of trials, the closer the data was to the theoretical probability.

C) The average obtained from 5 trials was as close to theoretical probability as the average obtained from 25 trials.

D) The average obtained from 10 trials was as close to theoretical probability as the average obtained from 20 trials.

You cannot buy it.

Step-by-step explanation:

$450 with a 20% percent discount would be $360

Add in a sales tax of 5.25%, and it amounts to $549 in total.

Since you only have $400, you cannot buy the bike.
