To simulate a random event with probability 0.65, we could select from 80 shuffled cards, with_______

of the cards marked as success.

What is 80*.65 number of cards marked?

To determine the number of cards marked as success, we can multiply the probability of success by the total number of cards.

In this case, the probability of success is 0.65 and the total number of cards is 80. Therefore, the number of cards marked as success would be:

Number of cards marked as success = Probability of success * Total number of cards
= 0.65 * 80
= 52

So, 52 of the cards would be marked as success.
