Question

Rolling dice-what is the probability of rolling a 1, 3, or 5? Two die are rolled? There are 36 possible outcomes that constitute the sample space. What is the probability of rolling two 6's? A deck of 52 cards contains-26 red and 26 black cards. What is the probability of drawing a red card? The blood groups of 100 people are distributed as follows: 25 have type A blood 32 have B blood type 35 have O blood type 8 have type AB blood. If a person from this group is selected at random, what is the probability that this person has blood type?

Explanation / Answer

17) P(rolling 1, 3 or 5) = 3/6 = 0.5

18) P(rolling two 6's) = 1/36 = 0.0278

19) P(red cards) = 26 / 52 = 0.5

20) P(A blood type) = 25 / 100 = 0.25
