1)Find the probability of getting a three first and then a four when the die is rolled twice.
The results are independent so (1/6)(1/6)= 1/36
2) Find the probability of drawing a heart or a club from a standard deck of cards
P(h or c) = P(h) + P(c)
These events are mutually exclusive so (13/52)+(13/52)=26/52
3)
Find the probability of drawing a heart or a black card from a standard deck of cards.
P(h or b) = P(h) + P(b) - P(b and h)
13/52 + 26/52 - 0/52= 39/52
