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
 one year ago

hartnn Group TitleBest 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

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