Question 167640
select on card from a standard deck. What is the probability of selecting a four, seven or a heart?
-------------------------
# of fours = 4 including a heart
# of sevens = 4 including a heart
# of hearts = 13 including a seven and a heart
-------------------------------
P(4, or 7 or heart) = (3+3+13)/52 = 19/52
