Question

If you randomly select a card from a well shuffled standard deck of 52 card what is the probability that the card you selected is a 7 or 8th round the solution to the 4 decimal place if necessary

Answer 1

Probabilities

There are 52 possible selections for the card (total number of cards).

From those possible selections, only the 7's and 8's are favorable.

There are 4 sevens and 4 eights, for a total of 8 favorable cases.

Thus, the required probability is:

$p=\frac{8}{52}$

Calculating, p = 0.1538
