Suppose Santana has a deck of cards and he chooses a card without looking. The deck has 52 cards. Each suit (hearts, spades, diamonds, and clubs) has 13 cards. What is the probability that Santana will choose a heart or diamond?
What is 50%
P (Hearts or diamond) = 26/52 = 1/2 = 0.050 = 50%

Sean surveyed 100 people randomly at school to see where they were going for Spring Break. If 34 of the students said they were traveling to Florida, how many students would Sean expect to travel to Florida if he surveyed 350 students?
119 Students.
34/100=X/350
350(0.34)=(x/350)350
X=119

Perla flipped a coin 100 times. Based on Theoretical probability, what is the expected results of Perla flipping the coin 100 times and it landing on tails?
What is 50%
P = 50/100 = 1/2 = 0.50 = 50%
