Suppоse yоu hаve а stаndard deck оf 52 playing cards and you randomly select 1 card and record whether or not the card that you drew was a "club". You then return to the card back to the deck and repeat this process a total of 6 times so that you end up drawing 6 cards total. Find the probability that less than 2 out of the 6 cards that you drew were clubs.  Make sure to type in your answer rounded to 2 decimal places.
