Okay so i have a choice i can either go for *a ten* or a *queen* I go for queen so,4/52 = 0.0769
 9 months ago

hartnnBest ResponseYou've already chosen the best response.4
'or' in probability means we add the individual probabilities 4/52 for queen + 4/52 for a ten (4+4)/52 will be final answer for d)...just simplify

Oh then that concept is confusing but okay *8/52?*
 9 months ago

hartnnBest ResponseYou've already chosen the best response.4
yes, 8/52 ...simplify that. same for last part just add total number of face cards + total # of 5's and total # of 4 of spade
 9 months ago

uriBest ResponseYou've already chosen the best response.0
Face cards are 12,total 5's are 4 and spade's are 4? So,12+4+4 =20/52 =0.3846153.

because the question doesn't ask of only spades only spades = 13 its ask for a "4 of spade" which is unique
