Question 409990: If a fair coin is flipped and a card is randomly drawn what is the probability that the coin will land heads up or the card will be a heart? Why?
I know the probability of a coin flip is 1/2 and the probability of drawing a heart is 1/4 but I am confused on what to do next. Please help. Thanks! Answer by stanbon(75887) (Show Source):

These outcomes are independent events
so you should multiply the individual
probabilities.
---
P(heads) = 1/2
P(heart) = 13/52 = 1/4
---
P(head and heart) = (1/2)(1/4) = 1/8
----
P(head or heart) = P(head)+p(heart)-P(head and heart)
= 1/2 + 1/4 - 1/8
---
= 4/8 + 2/8 - 1/8 = 5/8
